DUAL BAND WIRELESS LAN BASEBAND PROCESSOR DATA BRIEF - - - Features Tri Mode 802.11a, 802.11g and 802.11b pliant. Agile RF allows fully automated roaming between different modes. Implements data rates of 6, 9, 12, 18, 24, 36, 48 and 54 Mbps in 802.11a and 802.11g modes, using an advanced OFDM processor with channel equalizer. Implements data rates of 1, 2, 5.5 and 11 Mbps in 802.11b mode, using advanced RAKE and decision feedback equalization. Improved PA efficiency using digital predistortion linearization and active bias control. Gain and Phase imbalance correction improves Rx sensitivity. Supports receive antenna diversity for both bands Supports 802.11b short preamble. On-chip 10 bit ADC and DAC converters for I/Q data. On-chip 10 bit DAC for analog AGC control. On-chip 10 bit DACs to support DC offset correction in Zero-IF systems. On-chip 10 bit DAC, and dedicated I/O to provide transmit power control (TPC). On-chip general purpose 10 bit ADC for power supply monitoring, PA output power monitoring or temperature sense. Hardware assisted 40 and 128 bit WEP and WEP2 (TKIP) engine. Hardware assisted AES encryption. A low frequency standby clock and advanced power management extend battery life in portable equipment. Powerful 32 bit CPU and protocol accelerator implement the MAC functionality. On-chip system memory removes the need for external FLASH or SRAM reducing plexity and cost. Firmware is loaded from the host processor allowing automated software upgrade. Supports UART, Cardbus32 and Mini PCI interfaces to host processor.
