BCM88335L2CUBGT

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. 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.
