CircuitVision Analysis on the RF Transmit Path, RF Receive Path and Frequency Synthesizer of the Marvell 88W8686 802.11 a/b/g RF IC Transceiver

The is a Circuit Vision Design Analysis Report on Marvell 88W8686 WLAN System on Chip (SoC) solution supporting 802.11 a/b/g. The Marvell 88W8686 chip is advertised as the world’s first ultra-low-power, 90nm Wireless LAN (WLAN) single-chip solution. The device integrates an ARM compliant CPU, and high speed serial host interfaces. The advanced dual-band RF transceiver supports the IEEE 802.11 a/b/g standards. Marvel uses a thick Media Access Control (MAC) architecture in their design to offload the host CPU resulting in lower power consumption and increased system performance. The Marvel 88W8686 WLAN (SoC) device was located in iPhone.
