Libertas^™
Wireless LAN 802.11g(b) Client Chipset
88W8010 and 88W8310
PRODUCT OVERVIEW
The Marvell^¨ Libertas^ª 88W8010 and 88W8310 chipset comprises the worldÕs Þrst true, 2-chip 802.11g(b)
CMOS client solution. The 88W8010 is an optimized RF-baseband transceiver that integrates a near 20 dBm
power ampliÞer (23 dBm for 802.11b CCK signals), low noise ampliÞer, voltage-controlled oscillator, frequency
synthesizer, as well as other necessary RF and analog functions onto one chip. The 88W8310 product is a single
chip that combines the functions of the Direct Sequence Spread Spectrum (DSSS) and Orthogonal Frequency
Division Multiplexing (OFDM) baseband processor, Medium Access Control (MAC) processor, on-chip CPU, on-chip
memory, advanced security engine, and various host interfaces. The high level of integration, close interaction of
RF and digital functions, and a full implementation of the power of management functions speciÞed in IEEE
802.11 minimize the system power requirements. Together, the 88W8010 and 88W8310 chipset supports IEEE
802.11g data rates of 6, 9, 12, 18, 24, 36, 48, and 54 Mbps as well as 802.11b rates of 1, 2, 5.5, and 11 Mbps.
There is also support for proprietary data rates of 22 Mbps and 72 Mbps for client applications.
