The ML2712 is controlled using a three-wire programming interface and three control lines. The transmit circuits feature an RF down converter for a transmit frequency translation loop and a Wideband Phase Detector for a directly modulated VCO transmitter. An RF down converter mixer is provided for receive. All frequency generation circuits are integrated for the RF conversion, the 1LO VCO and PLL plus a 2LO VCO and PLL for use in dual conversion radios. In addition the ML2712 contains an 8 bit D/A & Comparator that may be used together as a tracking A/D for Received Signal Strength Indication measurement (RSSI).
