Avastar 88W8764

The Avastar 88W8764 is a highly integrated 4x4 wireless local area network (WLAN) system-on-chip (SoC), specifically designed to support high throughput data rates for next generation WLAN products. The device is designed to support IEEE 802.11n/a/g/b payload data rates.

The Marvell Avastar 88W8764 provides the combined functions of DSSS, OFDM, and MIMO baseband modulation, MAC, on-chip CPU, memory, host interfaces, and direct-conversion WLAN RF radio on a single integrated chip. The device supports 802.11n beamformer and beamformee functionality, enabling a simplified, integrated solution.

When combined with other Marvell solutions, significant range and throughput performance can be achieved.

Key Features

  • Single-chip integration of 802.11n/a/g/b wireless baseband, MAC, radio, CPU, memory, and host interface
  • 4x4 MIMO operation
  • Low power dissipation
  • 40 MHz crystal clock support

Marvell Beamforming Technology:

A specialized method of radio-frequency transmission used in Wi-Fi access points; beamforming enhances the signal reception at the client, extending the Wi-Fi signal coverage by two to four times. A feature of all Marvell Avastar SoCs, Marvell's beamforming technology doesn't require a special antenna nor will it incur any other cost increase of the wireless subsystem. The result is an increased throughput performance of up to 20x over existing technology, depending on the environment. Marvell's beamforming also outperforms other digital signal processing techniques for range extension by at least six times.

APPLICATIONS:

  • Personal computer systems
  • Wireless gateways, routers, and access points
  • Wireless client cards and bridges
  • Wireless home audio and video entertainment systems including TV, set-top boxes, media servers, and gaming platforms
