BCM4354 Data Sheet
Bluetooth + FM Subsystem Overview
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.
