 RRBFSBFS--B921AB921A1. RF Receiver Block1.1 Receiver PathThe receiver path uses a low IF scheme to down-convert the received bit signal for demodulation in the digital demodulator and bit synchronizer. The receiver path provides a high degree of linearity, an extended dynamic range, and high order on-chip channel filtering to ensure reliable operation in the noisy 2.4 GHz ISM band. The front-end topology, with built-in out-of-band attenuation, enables the device to be usedfrontend topology, with builtin outofband attenuation, enables the device to be used in most applications with no off-chip filtering. For integrated handset operation where the Bluetooth function is integrated close to the cellular transmitter, minimal external filtering is required to eliminate the desensitization of the receiver by the cellular transmit signal.1.1.1 Digital Demodulator and Bit synchronizerThe digital demodulator and bit synchronizer takes the low IF received signal and gy gperforms an optimal frequency tracking and bit synchronization algorithm.1.1.2 Receiver Signal Strength IndicatorThe BCM2046 radio provides an Receiver Signal Strength (RSSI) signal to the baseband so that the controller can take part in a Bluetooth power-controlled link by providing a metric of its own receiver signal strength to determine whether the transmitter should increase or decrease its output power.Page 1RBFS-B921A-AN-01-A
