BCM4334

Not Recommended for New Designs Preliminary Data Sheet BCM4334X Single Chip IEEE 802.11 a/b/g/n MAC/Baseband/Radio with Integrated Bluetooth 4.0 + HS and FM Receiver GENERAL DESCRIPTION The Broadcom® BCM4334X single-chip device provides the highest level of integration for a mobile or handheld wireless system, with integrated IEEE 802.11 a/b/g and single-stream IEEE 802.11n MAC/baseband/radio, Bluetooth 4.0 + HS, and FM radio receiver. It is designed to be used with external 2.4 GHz and 5 GHz front-end modules, which include power amplifiers, low-noise amplifiers, and T/R switches. Using advanced design techniques and process technology to reduce active and idle power, the BCM4334X is designed to address the needs of highly mobile devices that require minimal power consumption and compact size. It includes a power management unit which simplifies the system power topology and allows for operation directly from a mobile platform battery while maximizing battery life. FEATURES The BCM4334X implements the highly sophisticated Enhanced Collaborative Coexistence algorithms and hardware mechanisms, allowing for an extremely collaborative Bluetooth coexistence scheme along with coexistence support for external radios (such as cellular and LTE, GPS, WiMAX, and Ultra-Wideband) and a single shared 2.4 GHz antenna for Bluetooth and WLAN. As a result, enhanced overall quality for simultaneous voice, video, and data transmission on a handheld system is achieved. For the WLAN section, ...
