The Rx ADCs feature 55.1dB SNR and 73.4dBc SFDR at a 1.875MHz input frequency with a 7.5MHz clock frequency. The analog I/Q input amplifiers are fully differential and accept 1.024VP-P full-scale signals. Typical I/Q channel matching is ±0.01° phase and ±0.02dB gain.
The Tx DACs feature 77.2dBc SFDR at fOUT = 620kHz and fCLK = 7.5MHz. The analog I/Q full-scale output voltage is ±400mV differential. The Tx DAC commonmode DC level is programmable from 0.9V to 1.35V. The I/Q channel offset is adjustable. The typical I/Q channel matching is ±0.03dB gain and ±0.08° 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 MAX19705 operates on a single +2.7V to +3.3V analog supply and +1.8V to +3.3V digital I/O supply. The MAX19705 is specified for the extended (-40°C to +85°C) temperature range and is available in a 48-pin, thin QFN package. See a parametric table of the complete family of pin-compatible AFEs.
