Basis of Presentation and Significant Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	2. Basis of Presentation and Significant Accounting Policies The accompanying condensed consolidated financial statements as of March 31, 2017, and for the three and nine months ended March 31, 2017 and 2016 have been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto, included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2016. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair statement have been included. The condensed consolidated balance sheet as of June 30, 2016 has been derived from the audited consolidated financial statements as of that date but does not include all of the information and footnotes included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2016. The results of operations for the three and nine months ended March 31, 2017 are not necessarily indicative of the operating results to be expected for the full fiscal year or any future periods. Computation of Net Loss per Share Basic net loss per share is determined by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted net loss per share is determined by dividing net loss by the weighted average number of common shares used in the basic loss per share calculation plus the number of common shares that would be issued assuming conversion of all potentially dilutive securities outstanding under the treasury stock method. Dilutive securities of 5.4 million weighted shares and 5.1 million weighted shares were not included in the computation of diluted net loss per share for the three and nine months ended March 31, 2017, respectively, because such securities were anti-dilutive. Dilutive securities of 3.4 million weighted shares and 5.3 million weighted shares were not included in the computation of diluted net income per share for the three and nine months ended March 31, 2016, respectively because such securities were anti-dilutive. Concentration of Credit Risk Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash, cash equivalents, short-term investments and accounts receivable. As of March 31, 2017, all of the Company’s cash, cash equivalents and short-term investments were managed by multiple financial institutions. Accounts receivable are typically unsecured and are derived from revenue earned from customers. The Company performs ongoing credit evaluations of its customers and maintains allowances for potential credit losses. At June 30, 2016, the same value-added distributor accounted for 42% of the total accounts receivable Significant Accounting Policies The Company’s significant accounting policies are included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2016. Recent Accounting Pronouncements New Accounting Standards Recently Adopted In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-03, Accounting Changes and Error Corrections (Topic 250) and Investments – Equity Method and Joint Ventures (Topic 323): Amendments to SEC Paragraphs Pursuant to Staff Announcements at the September 22, 2017 and November 17, 2016 EITF Meetings, Recent Accounting Standards or Updates Not Yet Effective In May 2014, the FASB issued ASU 2014-9 Revenue from Contracts with Customers (Topic 606) Topic 605, Revenue Recognition rom August 2015 through December 2016, the FASB . These amendments are intended to improve and clarify the implementation guidance of Topic 606. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) In March 2016, the FASB issued ASU 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326 ): Measurement of Credit Losses on Financial Instruments Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses, which the FASB believes will result in more timely recognition of such losses. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments , which addresses the appropriate cash flow classification, including requirements to allocate certain components of these cash receipts and payments among operating, investing and financing activities for certain cash receipts and cash payments. The retrospective transition method, requiring adjustment to all comparative periods presented, is required unless it is impracticable for some of the amendments, in which case those amendments would be prospectively as of the earliest date practicable. This accounting guidance is effective for financial reporting periods beginning after December 15, 2017 with early adoption permitted. The Company is currently evaluating the impact that the adoption of this accounting guidance may have on its consolidated financial statements. In December 2016, the FASB issued ASU 2016-19, Technical Corrections and Improvements , which includes numerous technical corrections and clarifications to that are designed to remove inconsistencies in the board’s accounting guidance. Several provisions in this accounting guidance are effective immediately which did not have an impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, which clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill, and consolidation. The guidance is effective for annual financial reporting periods beginning after December 15, 2017. In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350) Simplifying the Test for Goodwill Impairment , which provides guidance to simplify the subsequent measurement of goodwill by eliminating the Step 2 procedure from the goodwill impairment test. An entity should perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The Company does not expect that its adoption of this guidance will have a material impact on its consolidated financial statements.

Fair Value Disclosure

Fair Value Disclosure	9 Months Ended

Fair Value Disclosure [Abstract]
Fair Value Disclosure	5. Fair Value Disclosure Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal market (or most advantageous market, in the absence of a principal market) for the asset or liability in an orderly transaction between market participants at the measurement date. Further, entities are required to maximize the use of observable inputs and minimize the use of unobservable inputs in measuring fair value, and to utilize a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. The three levels of inputs used to measure fair value are as follows: • Level 1 — Quoted prices in active markets for identical assets or liabilities. • Level 2 — Observable inputs other than quoted prices included within Level 1, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and inputs other than quoted prices that are observable or are derived principally from, or corroborated by, observable market data by correlation or other means. • Level 3 — Unobservable inputs that are supported by little or no market activity, are significant to the fair value of the assets or liabilities, and reflect the Company’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The tables below set forth the Company’s financial instruments and liabilities measured at fair value on a recurring basis (in thousands): March 31, 2017 Fair Value Level 1 Level 2 Level 3 Assets: Cash and cash equivalents: Money market funds $ 1,089 $ 1,089 $ - $ - Commercial paper 749 - 749 - Short-term investments: Corporate notes and commercial paper 21,093 - 21,093 - U.S. Government agency securities 27,153 - 27,153 - Total assets measured and recorded at fair value $ 50,084 $ 1,089 $ 48,995 $ - The above table excludes $54.8 million of cash balances on deposit at banks. June 30, 2016 Fair Value Level 1 Level 2 Level 3 Assets: Cash and cash equivalents: Money market funds $ 3,533 $ 3,533 $ - $ - Short-term investments: Corporate notes and commercial paper 26,363 - 26,363 - U.S. Government agency securities 20,070 - 20,070 - Total assets measured and recorded at fair value $ 49,966 $ 3,533 $ 46,433 $ - The above table excludes $58.2 million of cash balances on deposit at banks. Money market funds are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices in active markets. Short-term investments are classified within Level 2 of the fair value hierarchy because they are valued based on other observable inputs, including broker or dealer quotations, or alternative pricing sources. When quoted prices in active markets for identical assets or liabilities are not available, the Company relies on non-binding quotes from independent pricing services. Non-binding quotes are based on proprietary valuation models prepared by independent pricing services. These models use algorithms based on inputs such as observable market data, quoted market prices for similar instruments, historical pricing trends of a security as relative to its peers, internal assumptions of the independent pricing service and statistically supported models. The Company corroborates the reasonableness of non-binding quotes received from the independent pricing service by comparing them to the (a) actual experience gained from the purchases and redemption of investment securities, (b) quotes received on similar securities obtained when purchasing securities and (c) monitoring changes in ratings of similar securities and the related impact on the fair value. The types of instruments valued based on other observable inputs include U.S. government agency securities, corporate notes and commercial paper. The Company reviewed financial and non-financial assets and liabilities and concluded that there were no other-than-temporary impairment charges during the three and nine months ended March 31, 2017 and 2016. The Company reviews the fair value hierarchy on a quarterly basis. Changes in the ability to observe valuation inputs may result in a reclassification of levels of certain securities within the fair value hierarchy. The Company recognizes transfers into and out of levels within the fair Assets and Liabilities That Are Measured at Fair Value on a Nonrecurring Basis Non-financial assets such as goodwill, intangible assets, and property, plant, and equipment are evaluated for impairment and adjusted to fair value using Level 3 inputs, only when impairment is recognized. Fair values are considered Level 3 when management makes significant assumptions in developing a discounted cash flow model based upon a number of considerations including projections of revenues, earnings and a discount rate. In addition, in evaluating the fair value of goodwill impairment, further corroboration is obtained using the Company’s market capitalization. There were no indicators of impairment during the three and nine months ended March 31, 2017 and 2016

Income Taxes [Abstract]
Income Taxes	7. Income Taxes The Company recorded an income tax provision of $0.2 million and income tax benefit of $0.3 million for the three months ended March 31, 2017 and 2016 , respectively. The Company recorded an income tax provision of $0.5 million for the both the nine months ended March 31, 2017 and 2016 , respectively. The Company maintains liabilities for uncertain tax positions. As of March 31, 2017 and June 30, 2016, the total amount of unrecognized tax benefits was $6.9 million and $6.3 million, respectively. Of the total of $6.9 million of unrecognized tax benefit as or March 31, 2017, $0.2 million, if recognized, would impact the effective tax rate. The Company does not expect its unrecognized tax benefits to change materially over the next 12 months. While management believes that the Company has adequately provided for all tax positions, amounts asserted by tax authorities could be greater or less than the Company’s current position. Accordingly, the Company’s provisions for federal, state, and foreign tax related matters to be recorded in the future may change as revised estimates are made or as the underlying matters are settled or otherwise resolved. The Company’s primary tax jurisdiction is in the United States. For federal and state tax purposes, the tax years 2002 through 2015 remain open and subject to tax examination by the appropriate federal or state taxing authorities.

Derivative Instruments and Hedging Activities [Abstract]
Derivative Instruments and Hedging Activities	16. Derivative Instruments and Hedging Activities In the normal course of business, the Company is exposed to fluctuations in interest rates and the exchange rates associated with foreign currencies. During the three and nine months ended March 31, 2017, the Company used derivative instruments to reduce the volatility of earnings associated with changes in foreign currency exchange rates. The Company used foreign exchange forward contracts to mitigate the gains and losses generated from the re-measurement of certain foreign monetary assets and liabilities, primarily including cash balances, third party accounts receivable and intercompany transactions recorded on the balance sheet. These derivatives are not designated and do not qualify as hedge instruments. Accordingly, changes in the fair value of these instruments are recognized in other income and expenses during the period of change. These derivatives have maturities of approximately one month. The foreign exchange forward contracts outstanding as of March 31, 2017 were entered into by the Company on the last business day of the period. Given the relatively short duration such contracts are outstanding in relation to changes in potential market rates; the change in the fair value is not material and is not reflected either as an asset or a liability. The following table presents the gross notional value of all of the Company’s foreign exchange forward contracts outstanding as of March 31, 2017 and June 30, 2016 (in thousands): March 31, 2017 Local Currency Amount Notional Contract Amount (USD) Australian dollar $ 1,580 $ 1,188 British pound £ 1,830 2,267 Canadian dollar $ 1,190 883 Euro € 670 711 Total $ 5,049 June 30, 2016 Local Currency Amount Notional Contract Amount (USD) Australian dollar $ 1,800 $ 1,316 British pound £ 830 1,088 Canadian dollar $ 940 718 Euro € 1,500 1,650 Total $ 4,772

Basis of Presentation and Significant Accounting Policies [Abstract]
Computation of Net Loss per Share	Computation of Net Loss per Share Basic net loss per share is determined by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted net loss per share is determined by dividing net loss by the weighted average number of common shares used in the basic loss per share calculation plus the number of common shares that would be issued assuming conversion of all potentially dilutive securities outstanding under the treasury stock method. Dilutive securities of 5.4 million weighted shares and 5.1 million weighted shares were not included in the computation of diluted net loss per share for the three and nine months ended March 31, 2017, respectively, because such securities were anti-dilutive. Dilutive securities of 3.4 million weighted shares and 5.3 million weighted shares were not included in the computation of diluted net income per share for the three and nine months ended March 31, 2016, respectively because such securities were anti-dilutive.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash, cash equivalents, short-term investments and accounts receivable. As of March 31, 2017, all of the Company’s cash, cash equivalents and short-term investments were managed by multiple financial institutions. Accounts receivable are typically unsecured and are derived from revenue earned from customers. The Company performs ongoing credit evaluations of its customers and maintains allowances for potential credit losses. At June 30, 2016, the same value-added distributor accounted for 42% of the total accounts receivable

Recent Accounting Pronouncements	Recent Accounting Pronouncements New Accounting Standards Recently Adopted In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-03, Accounting Changes and Error Corrections (Topic 250) and Investments – Equity Method and Joint Ventures (Topic 323): Amendments to SEC Paragraphs Pursuant to Staff Announcements at the September 22, 2017 and November 17, 2016 EITF Meetings, Recent Accounting Standards or Updates Not Yet Effective In May 2014, the FASB issued ASU 2014-9 Revenue from Contracts with Customers (Topic 606) Topic 605, Revenue Recognition rom August 2015 through December 2016, the FASB . These amendments are intended to improve and clarify the implementation guidance of Topic 606. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) In March 2016, the FASB issued ASU 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326 ): Measurement of Credit Losses on Financial Instruments Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses, which the FASB believes will result in more timely recognition of such losses. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments , which addresses the appropriate cash flow classification, including requirements to allocate certain components of these cash receipts and payments among operating, investing and financing activities for certain cash receipts and cash payments. The retrospective transition method, requiring adjustment to all comparative periods presented, is required unless it is impracticable for some of the amendments, in which case those amendments would be prospectively as of the earliest date practicable. This accounting guidance is effective for financial reporting periods beginning after December 15, 2017 with early adoption permitted. The Company is currently evaluating the impact that the adoption of this accounting guidance may have on its consolidated financial statements. In December 2016, the FASB issued ASU 2016-19, Technical Corrections and Improvements , which includes numerous technical corrections and clarifications to that are designed to remove inconsistencies in the board’s accounting guidance. Several provisions in this accounting guidance are effective immediately which did not have an impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, which clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill, and consolidation. The guidance is effective for annual financial reporting periods beginning after December 15, 2017. In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350) Simplifying the Test for Goodwill Impairment , which provides guidance to simplify the subsequent measurement of goodwill by eliminating the Step 2 procedure from the goodwill impairment test. An entity should perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The Company does not expect that its adoption of this guidance will have a material impact on its consolidated financial statements.
