The radio signal is taken from 75 balanced RF input and amplified by an LNA. The mixers are driven by two quadrature signals which are locally generated from a VCO signal running at twice the frequency. The output signals in the I signal path and Q signal path are bandpass filtered by a polyphase bandpass filter for channel filtering and image rejection. The output of the lowpass filters is amplified by a VGA to the optimal input range for the A/D converters. Further filtering is done in digital filters. The digital part demodulates the GFSK coded bit stream by evaluating the phase information in the I and Q signals. The digital part recovers the receive bit clock. It extracts RSSI data by calculating the signal strength. Overall automatic gain amplification in the receive path is controlled by the digital part. Transmitter The transmitter takes the serial input transmit data from the base-band. This data is GFSK modulated to I and Q signals. The Tx bit clock is provided to the base-band for synchronization. The output of the digital part is converted to analogue signals which are lowpass filtered before being sent to direct up-conversion mixers. The quadrature up-conversion mixers use the same LO as the receiver. 0dBm output power at the antenna port is achieved with an internal PA, which has 75 balanced RF output. Optional power control is available. PLL The on-chip VCO is part of a PLL, the frequency is programmed for the RF channels by the digital part. The tank resonator circuitry for the VCO is completely integrated. Process variations on the VCO center frequency are calibrated out automatically. Also the RC time constants for the analogue lowpass filters are automatically calibrated on chip. Base-band interface Unidirectional BlueRF compatible interface is used to control all functions of radio transceiver. The unidirectional RXMODE2 is supported. STLC2150 has also the capability to provide the recovered clock and the aligned data to the base-band (Rxmode2+). 4 wires serial JTAG interface is used to access the internal registers. Also JTAG is used to set channel number and read RSSI. Crystal oscillator The STLC2150 has a crystal oscillator to generate 13 MHz reference clock for internal use and for the baseband chip. Also a 3.2 or 32 kHz clock for low power modes operation can be provided. 5/10 STLC2150 GENERAL SPECIFICATION All the provided values are specified over the operational conditions (VDD and temperature) according to the Bluetooth(R) v.1.2 specification. Receiver To comply with the Bluetooth(R) norm, an external RF filter is required to provide minimum 17dB of attenuation in the bands: 30MHz - 2000MHz and 3000MHz - 12.75GHz. All specification below are measured at the antenna port.

The external crystal must be connected to the pads XTAL13I and XTAL13O. The frequency specification of 20 ppm can be achieved by 2 different ways: 1. by external components choice (default); 2. by internal tuning (with internal capacitors as defined by the control word stored in the registers. The control word allows modifying the value of the capacitor connected to the oscillator pads. The total capacitance (including the parasitic capacitors) must be about 16 pF. The variable capacitor is implemented as a capacitor array of about 255 x 90 fF.
