The MAX19707 is an ultra-low-power, mixed-signal analog front-end (AFE) designed for power-sensitive communication equipment. Optimized for high dynamic performance at ultra-low power, the device integrates a dual, 10-bit, 45Msps receive (Rx) ADC; dual, 10-bit, 45Msps transmit (Tx) DAC; three fast-settling 12-bit aux-DAC channels for ancillary RF front-end control; and a 10-bit, 333ksps housekeeping aux-ADC. The typical operating power in Tx-Rx FAST mode is 84.6mW at a 45MHz clock frequency.
The Rx ADCs feature 54.2dB SNR and 71.2dBc SFDR at fIN = 5.5MHz and fCLK = 45MHz. The analog I/Q input amplifiers are fully differential and accept 1.024VP-P full-scale signals. Typical I/Q channel matching is ±0.03° phase and ±0.01dB gain.
The Tx DACs feature 73.2dBc SFDR at fOUT = 2.2MHz and fCLK = 45MHz. The analog I/Q full-scale output voltage is ±400mV differential. The Tx DAC common-mode DC level is programmable from 0.71V to 1.05V. The I/Q channel offset is programmable to optimize radio lineup sideband/carrier suppresion. The typical I/Q channel matching is ±0.01dB gain and ±0.07° phase.
The Rx ADC and Tx DAC share a single, 10-bit parallel, high-speed digital bus allowing half-duplex operation for time-division duplex (TDD) applications. A 3-wire serial interface controls power-management modes, the aux-DAC channels, and the aux-ADC channels.
The MAX19707 operates on a single 2.7V to 3.3V analog supply and 1.8V to 3.3V digital I/O supply. The MAX19707 is specified for the extended (-40°C to +85°C) temperature range and is available in a 48-pin, thin QFN package. The Selector Guide at the end of the data sheet lists other pin-compatible versions in this AFE family.
