GENERAL DESCRIPT ION

The Broadcom® BCM88335 single-chip device

provides the highest level of integration for

Automotive In-Vehicle Infotainment connectivity

systems with integrated single-stream IEEE 802.11ac

MAC/baseband/radio, Bluetooth 4.1. In IEEE

802.11ac mode, the WLAN operation supports rates

of MCS0–MCS9 (up to 256 QAM) in 20 MHz, 40 MHz,

and 80 MHz channels for data rates up to

433.3 Mbps. In addition, all the rates specified in IEEE

802.11a/b/g/n are supported. Included on-chip are

2.4 GHz and 5 GHz transmit amplifiers, and receive

low-noise amplifiers. Optional external PAs, LNAs,

and antenna diversity are also supported.

The BCM88335 offers an SDIO v3.0 interface for high

speed 802.11ac connectivity. The Bluetooth host

controller is interfaced over a 4-wire high speed

UART and includes PCM for audio.

The BCM88335 brings the latest mobile connectivity

technology to automotive infotainment, telematics

and rear seat entertainment. Offering Automotive

Grade 3 (–40°C to +85°C) temperature performance,

the BCM89335 is tested to AECQ100 environmental

stress guidelines and manufactured in ISO9001 and

TS16949 certified facilities.

The BCM88335 implements highly sophisticated

enhanced collaborative coexistence hardware

mechanisms and algorithms, which ensure that

WLAN and Bluetooth collaboration is optimized for

maximum performance. In addition, coexistence

support for external radios (such as LTE cellular,

GPS, and WiMAX) is provided via an external

interface. As a result, enhanced overall quality for

simultaneous voice, video, and data transmission is

achieved.
