PLX TECHNOLOGY, INC. REPORTS FIRST-QUARTER RESULTS

SUNNYVALE, Calif. - (April 16, 2003) - PLX Technology, Inc. (NASDAQ: PLXT) today
announced financial results for the first quarter ended March 31, 2003.

For the first quarter ended March 31, 2003, the Company reported net revenues of
$8.5 million, a 16 percent decrease from the $10.1 million reported for the
first quarter of 2002 and a one percent decrease from the $8.6 million reported
for the fourth quarter of 2002. Net losses under generally accepted accounting
principles (GAAP), which includes the effect of acquisition-related costs were
$816,000, or $0.04 per share, for the first quarter of 2003, compared with net
losses under GAAP of $271,000, or $0.01 per share, for the prior year quarter.

Pro forma net losses for the first quarter ended March 31, 2003, which excludes
the effect of acquisition-related costs, were $226,000, or $0.01 per share
(diluted), compared to pro forma net income of $514,000, or $0.02 per share
(diluted), for the prior year quarter. A reconciliation between net losses on a
GAAP basis and pro forma net losses is provided in a table immediately following
the Pro Forma Consolidated Statements of Operations.

The Company's gross margins in the first quarter were 70 percent. As a result of
selling some previously written-down inventory, the Company recorded a benefit
of approximately $204,000, or two gross margin points in the first quarter.

Cash and investments decreased to $21.3 million at March 31, 2003 from $21.7
million at December 31, 2002.

"In the first quarter our new product initiatives continued to show results,"
said Michael Salameh, president of PLX. "Our 66MHz PCI chips account for over
10 percent of our business and are used in approximately 30 customer designs. In
the first quarter, we added over a dozen new design wins around our 66MHz
products. Also in the quarter, several communication-equipment suppliers
developed new products using PLX's HyperTransport chips and are now in the
software development and system validation stage. The PCI-Express standard, the
focus of our new product development efforts, gained momentum as Intel and other
industry leaders announced products that incorporate this new interconnect.

"We estimate second-quarter revenues to be between $8.2 million and $9.2
million. We are projecting a wide range because turns business has been variable
and unpredictable. We anticipate that second-quarter operating expenses on a
GAAP basis will be between $6.6 million and $6.8 million and on a pro forma
basis (which excludes the effect of acquisition-related costs of approximately
$500,000 for the quarter) will be between $6.1 million and $6.3 million. We
expect gross margins to remain in the 65 to 70 percent range."

The Company will be conducting a conference call today at 2:00 p.m. (PST) to
discuss its first-quarter financial results. There will also be a live Webcast
and a replay of the conference call that will be available through the Investors
section of the PLX Web site at www.plxtech.com until April 23, 2003. The Webcast
can also be accessed through www.ccbn.com.

Event archives are normally available one to two hours after the event ends. For
the live event, listeners should go to the Web site at least fifteen minutes
before the event starts to download and install any necessary audio software.
