MAX19713：10-Bit, 45Msps, Full-Duplex, Analog Front-End

Ultra-Low Power AFE with Integrated Tx DACs, Rx ADCs, and Auxiliary Control Data Converters

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-P full-scale signals. Typical I/Q channel matching is ±0.03 phase and ±0.02dB gain. The Tx DACs feature 70.3dBc SFDR at fOUT = 2.2MHz and fCLK = 45MHz. The analog I/Q full-scale output voltage range is ±400mV differential. The output DC common-mode voltage is selectable from 0.71V to 1.06V. The I/Q channel offset is adjustable to optimize radio lineup sideband/carrier suppression. Typical I/Q channel matching is ±0.01dB gain and ±0.05° phase. Two independent 10-bit parallel, high-speed digital buses used by the Rx ADC and Tx DAC allow full-duplex operation for frequency-division duplex applications. The Rx ADC and Tx DAC can be disabled independently to optimize power management. A 3-wire serial interface controls power-management modes, the aux-DAC channels, and the aux-ADC channels. The MAX19713 operates on a single 2.7V to 3.3V analog supply and 1.8V to 3.3V digital I/O supply. The MAX19713 is specified for the extended (-40°C to +85°C) temperature range and is available in a 56-pin, thin QFN package. The Selector Guide at the end of the data sheet lists other pin-compatible versions in this AFE family. For time-division duplex (TDD) applications, refer to the MAX19705–MAX19708 AFE family of products.
