Abstract

A WLAN SoC for video applications handles IEEE 802.11a/b/g and supports PHY data rates to 108 Mbit/s. The SoC implements two chain maximum ratio combining and beamforming. Video features include a jitter removal system and MPEG-TS packet aggregation. Measured results on the 7.2mm×7.2mm IC using a 0.18 μm CMOS process demonstrate throughput improvements in both RX and TX.
