BCM2001 Bluetoothtransceiver integrated radio transceiver device, optimized 2.4-GHz Bluetooth wireless systems. designed provide low-power, low-cost, robust communication applications operating globally available 2.4-GHz unlicensed band. fully compliant with Bluetooth Specification meets exceeds requirements, where appropriate, provide highest communication link quality service. BCM2001 features simple, innovative shared architecture that enables high-performance radio implementation single CMOS chip. proprietary design generates quadrature signals 2.4-GHz band both transmitter receiver. locked 12-MHz, free-running crystal oscillator. frequency agile covers Bluetooth frequency-hopping channels. proprietary self-calibrating structure allows both excellent phase noise fast frequency hopping covering entire band. receiver front consists low-noise amplifier image reject mixer, which perform well without costly band pass filter. Balanced mixer structures accurate quadrature signals allow excellent noise figure strong image rejection.
frequency allows high performance amplifier filter designs CMOS. bandpass filter structure features selfcalibration circuitry that automatically adjusts circuit elements compensate process variation. This eliminates tuning ensures that process temperature variation uniform across devices. amplifiers provide limiting function that following stages always constant signal level regardless input level. RSSI signal also generated these amplifiers system determine signal strength. signal then filtered further, demodulated, finally sent slicer generate logic level data output. GFSK transmit signal first generated baseband proprietary modulator. then filtered upconverted using quadrature signals. signal then boosted class Bluetooth output power level power amplifier. Four output power levels digitally programmable from full power power 8-dB steps. BCM2001 controlled BlueRF unidirectional interface. BlueRF Bluetooth industry standard specification that provides compatibility between Bluetooth baseband chips. This interface provides control various sections chip, defines data transfers, allows access various internal registers device.
