This CMOS IC contains the analog functions required in the transceiver:
s [0..12MHz] receive and transmit signal frequency band
s 35MHz 14bit digital to analog conversion
s 35MHz 14bit analog to digital conversion
s Programmable gain amplifier in the TX path for optimum transmit power setting; the PGA is a pre-
amplifier for the external line driver
s RX filtering for noise reduction; TX filtering for slew rate reduction
s RC tuning for filter cut-off frequency control
s Clock generation based on a voltage controlled crystal oscillator; fine tuning by means of external
capacitors.
s Serial control interface to configure the component in normal mode and in test mode
s 100-pin TQFP package (14x14mm)
s Power consumption 500mW Typ.
s BiCMOS6 technology (0.35µm)
s Single 3.0V up to 3.6V supply
s Extended temperature range
3/8
