BCM4330 Preliminary Data Sheet
Bluetooth + FM Subsystem Overview
Section 4: Bluetooth + FM Subsystem Overview
The Broadcom BCM4330 is a Bluetooth 4.0 + EDR-compliant, baseband processor/ 2.4 GHz transceiver with an
integrated FM/ RDS/RBDS receiver and FM/RDS transmitter. 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 BCM4330 is the optimal solution for any Bluetooth voice and/or data application that also requires an FM
radio receiver and transmitter. 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 input and
output, as well as I2S and PCM interfaces. The BCM4330 incorporates all Bluetooth 4.0 features including
Secure Simple Pairing, Sniff Subrating, and Encryption Pause and Resume.
The BCM4330 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.
