Section 4: Bluetooth + FM Subsystem

Overview

The Broadcom BCM4354 is a Bluetooth 4.1 + EDR-compliant, baseband processor/2.4 GHz transceiver with

an integrated FM/RDS/RBDS receiver. It features the highest level of integration and eliminates all critical

external components, thus minimizing the footprint, power consumption, and system cost of a Bluetooth plus

FM radio solution.

The BCM4354 is the optimal solution for any Bluetooth voice and/or data application that also requires an FM

radio receiver. The Bluetooth subsystem presents a standard Host Controller Interface (HCI) via a high-speed

UART and PCM for audio. The FM subsystem supports the HCI control interface, analog output, as well as I2S

and PCM interfaces. The BCM4354 incorporates all Bluetooth 4.1 features including Secure Simple Pairing,

Sniff Subrating, and Encryption Pause and Resume.

The BCM4354 Bluetooth radio transceiver provides enhanced radio performance to meet the most stringent

mobile phone temperature applications and the tightest integration into mobile handsets and portable devices.

It is fully compatible with any of the standard TCXO frequencies and provides full radio compatibility to operate

simultaneously with GPS, WLAN, and cellular radios.

The Bluetooth transmitter also features a Class 1 power amplifier with Class 2 capability.
