Objective specification
Bluetooth RF Transceiver
FEATURES * Low cost solution for a Bluetooth radio * Fully integrated receiver with high sensitivity * Integrated low phase noise VCO * Dedicated Bluetooth Phase-Locked Loop (PLL) synthesizer * 4 dBm programmable transmitter preamplifier with an integrated switch * 3-line serial interface bus * Low current consumption from 3.0 V supply. APPLICATIONS 2400 to 2497 MHz Bluetooth radio transmission and reception in the Industrial Scientific and Medical (ISM) band. GENERAL DESCRIPTION The UAA3558 BiCMOS device is a low power, highly integrated circuit. It features a fully integrated receiver, from antenna filter output to the demodulated data output,
UAA3558
an integrated VCO, a synthesizer to implement Bluetooth channel frequencies, and a transmitter preamplifier to drive either the switch diode to antenna or a power amplifier. The synthesizer's main divider is driven by the prescaler output in the range of 2400 to 2497 MHz and programmed via a 3-wire serial bus. The reference divider ratio can be programmed to 12, 13, 16 or 26. Outputs of the main and reference dividers drive a phase comparator, where a charge pump produces phase error current pulses for integration in an external loop filter. The charge-pump current (phase comparator gain) is set to 3.5 mA. The synthesizer is programmed and switches on 200 s before the desired slot to lock the VCO to the required channel frequency. Just before the desired slot, the synthesizer is switched off, allowing open loop modulation of the VCO during transmission. The device is designed to operate from 3.0 V nominal supplies. Separate power and ground pins are provided to the different parts of the circuit. The ground leads should be connected together externally to prevent large currents flowing across the IC, which would cause damage. All VCC pins must also be at the same potential (VCC).
