SANTA CLARA, California, January 2 /PRNewswire/ --

- New Marvell TopDog 11n-450 Offers Peak Performance for PCs, Notebooks, 
Routers, Printers and Consumer Electronics Devices

Marvell (Nasdaq: MRVL) announced today the Marvell(R) TopDog(R) 11n-450,
an 802.11n 3x3 WLAN solution with three spatial streams, the industry's first
802.11n chip operating at 450 Megabits-per-second (Mbps). With maximum
bandwidth more than eight times faster than 802.11g 54 Mbps versions and 1.5
times faster than current 802.11n 300 Mbps offerings, the new product will
enable significant performance enhancements for notebooks and desktop PCs,
printers, routers, set top boxes, digital TVs, gaming devices and DVD players
and recorders. The TopDog 11n-450 provides 500 percent increased range over
802.11g, as well as 160 percent increased range compared to competing 802.11n
solutions.

"Marvell is first-to-market with an 802.11n 450 Mbps solution so
manufacturers can deliver industry-leading wireless range and performance to
consumers who are seeking faster and more powerful Wi-Fi capabilities," said
Sameer Bidichandani, senior director of technology strategy, Marvell
Semiconductor. "Compliant with the 802.11n specification, the new Marvell
TopDog 11n-450 chip also offers Marvell-engineered enhancements to the
specification, such as Special Time Block Coding (STBC), that helps maintain
higher throughput over longer distances."

For example, a user can move further from their wireless source while
performing real-time streaming video in multiple sessions, without
experiencing weaker signal strength, freezing frames or slower throughput.

The TopDog 11n-450 delivers 3x3 capabilities with three transmitters and
three receivers, and is built on 90-nanometer (nm) CMOS process technology
making it a lower-power, lower-cost solution on top of its higher range and
performance. The product is backward-compatible with previous 802.11a, b, g
and n versions and currently sampling. It is expected to begin shipping in
volume next quarter.

Marvell will be showcasing the new Marvell TopDog 11n-450, as well as its
cellular, video processing and power efficient products at CES Booth # 30651
in the South Hall.
