Description

The MAX19713 is an ultra-low-power, highly integrated mixed-signal analog front-end (AFE) ideal for wideband communication applications operating in full-duplex (FD)mode. Optimized for high dynamic performance and 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 FD mode is 91.8mW at a 45MHz clock frequency. The Rx ADCs feature 54dB SINAD and 72.2dBc SFDR at 5.5MHz input frequency with a 45MHz clock frequency. The analog I/Q input amplifiers are fully differential and accept 1.024VP-Pfull-scale signals. Typical I/Q channel matching is ±0.03 phase and ±0.02dB gain.
