The Rx ADCs feature 54.8dB SINAD and 79.8dBc SFDR at 3.3MHz 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 ±0.01dB gain.
The Tx DACs feature 73.8dBc SFDR at fOUT = 620kHz and fCLK = 7.5MHz. The analog I-Q full-scale output voltage range is ±400mV differential. The output DC common- mode voltage is from 0.89V to 1.36V. The I/Q channel offset is adjustable to optimize radio lineup sideband/ carrier suppression. Typical I-Q channel matching is ±0.01dB gain and ±0.15° 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 MAX19710 operates on a single 2.7V to 3.3V analog supply and 1.8V to 3.3V digital I/O supply. The MAX19710 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.
