The MAX19712 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, 22Msps receive (Rx) ADC; dual 10-bit, 22Msps 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 50.4mW at a 22MHz clock frequency.
The Rx ADCs feature 54.7dB SINAD and 75.6dBc SFDR at 5.5MHz input frequency with a 22MHz 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 72.9dBc SFDR at fOUT = 2.2MHz and fCLK = 22MHz. 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 ±0.1° 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 MAX19712 operates on a single 2.7V to 3.3V analog supply and 1.8V to 3.3V digital I/O supply. The MAX19712 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.

MAX19713EVCMODU
Evaluation Kits/Evaluation Systems for the MAX19710, MAX19712, and MAX19713
Product Detail
The MAX19710–MAX19713 evaluation systems (EV systems) consist of MAX19710–MAX19713 evaluation kits (EV kits), a companion Maxim command module (CMODUSB) interface board, and software. Order the complete EV system (see the Ordering Information in the full data sheet) for comprehensive evaluation of the MAX19710–MAX19713 using a personal computer. Order the EV kit if the command module has already been purchased with a previous Maxim EV system, or for custom use in other microcontroller-based (µC) systems.
The MAX19710–MAX19713 EV kits are fully assembled and tested PCBs that contain all the components necessary to evaluate the performance of the MAX19710–MAX19713 analog front-ends (AFEs). These AFEs integrate a dual-receive analog-to-digital converter (Rx ADC), a dual-transmit digital-to-analog converter (Tx DAC), a 1.024V internal voltage reference, three low-speed serial DACs, and one low-speed serial ADC. The EV kit boards accept AC- or DC-coupled, differential or single-ended analog inputs for the Rx ADC and include circuitry that converts the Tx DAC differential output signals to single-ended analog outputs. The EV kits include circuitry that generates a clock signal from an AC sine-wave input signal. The EV kits operate from a +3.0V analog power supply, a +1.8V digital power supply, a +3.0V clock power supply, and ±5V bipolar power supplies.
The Maxim command module interface board (CMODUSB) allows a PC to use its USB port to emulate an SPI™ 3-wire interface. Windows® 98SE/2000/XP-compatible software, which can be downloaded from www.maximintegrated.com/evkitsoftware, provides a user-friendly interface to exercise the features of the MAX19710–MAX19713. The program is menu driven and offers a graphical user interface (GUI) with control buttons and a status display.
Applications
- Broadband Access Radio
- Portable Communication Equipment
- Private Mobile Radio
