The STLC2150 is a fully integrated Bluetooth single chip radio transceiver. Together with a BB processor, like STLC2410, it offers a compact and complete solution for short-range wireless connectivity for a variety of applications. The STLC2150 implements a low-IF receiver for Bluetooth modulated input signals and no external IF filtering is required. The GFSK demodulator is fully integrated and supplies digital output data and RSSI. The transmit section features a fully integrated GFSK modulator, followed by a direct up-conversion stage, giving an output signal of 0 dBm. Optional power control is available. On-chip VCO covers full Bluetooth band and contains all of the tank resonator circuitry. Unidirectional BlueRF compatible interface and 4 wires serial JTAG interface are used to control all functions of radio transceiver, enabling operation with wide range of BB processors.
