(MRVL) - Get Marvell Technology Group Ltd. Report

offered a hint that the tech sector is poised to rebound Monday,


its second-quarter revenue forecast.

The Santa Clara, Calif.-based firm now expects sales between $600 million and $630 million, compared to its earlier projection of $540 million to $580 million.

As a key


manufacturer, Marvell's improved outlook could

bode well

for the broader tech sector, which has suffered during the global economic slowdown.

"We are optimistic in our near-term outlook based on the improved order rate we have experienced so far in our second quarter," said Dr. Sehat Sutardja, Marvell's CEO. "We believe

this generally signals some strengthening in our customers' expectations for their businesses."

Despite Marvell's positive outlook, shares of the company dipped 53 cents, or 4.4%, to $11.48, as the Nasdaq fell 3.35%. Rival

Storage accounted for more than half of Marvell's sales during its recent first quarter, and the firm also sells silicon for mobile handsets, PCs, switches and wireless networks.

"We are reiterating our positive outlook on MRVL following this upside surprise," wrote Avi Cohen, an analyst at Avian Securities, in a note released Monday, adding that the ripple effect will reach other parts of the tech sector.

"While Marvell did not point to a specific area of strength as catalyzing its upside, Western Digital remains Marvell's most significant account and we believe upside of this magnitude is unlikely without a strong Western Digital contribution," he added.

Shares of Western Digital, however, retreated with the broader tech market Monday, falling $1.09, or 4.3%, to $24.33.

Despite its bullish guidance, Marvell also struck a conservative tone Monday. "Even with the recent pick-up in demand for our products, we encourage everyone to remain cautious of the demand environment for the next few quarters, "said Sutardja, in a statement.
