This RF transceiver IP is a complete radio front-end optimized for Bluetooth SoC implementation integrating Basic Rate (BR), Enhanced Data Rate (EDR), Low Energy (LE) features fully compatible with the Bluetooth 4.2 specification. It has fully integrated power amplifiers, RF switch, a fractional-N synthesizer, and LDOs for minimum BOM and PIN counts. A special LPO for the high Sleep Clock Accuracy (SCA) is also integrated for the low power Bluetooth (BLE) applications. The IP also supports various radio calibration functions such as LPO frequency calibration, TRX IQ mismatch calibration, LO feedthrough calibration, DC offset cancellation, fast AGC, VCO calibration, VCO temp variation compensation, bias calibration, LPF corner frequency compensation, battery monitoring, and temperature monitoring. The internal, digitally-controlled gain stages at the RF and BB levels provide both low noise figure and large dynamic range of the receiver. The transmitter has more than 30dB gain range, providing a wide output power range while the cutoff frequency of the baseband filters are calibrated with an internal RC compensation scheme. A crystal oscillator, which is connected to a low cost external crystal, is also integrated. The SPI interface controls most of the transceiver functions.
