The MAX19707 is an ultra-low-power, mixed-signal analog front-end (AFE) designed for power-sensitive communication equipment. Optimized for high dynamic performance at 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 Tx-Rx FAST mode is 84.6mW at a 45MHz clock frequency.

The Rx ADCs feature 54.2dB SNR and 71.2dBc SFDR at fIN = 5.5MHz and fCLK = 45MHz. 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 ±0.01dB gain.

The Tx DACs feature 73.2dBc SFDR at fOUT = 2.2MHz and fCLK = 45MHz. The analog I/Q full-scale output voltage is ±400mV differential. The Tx DAC common-mode DC level is programmable from 0.71V to 1.05V. The I/Q channel offset is programmable to optimize radio lineup sideband/carrier suppresion. The typical I/Q channel matching is ±0.01dB gain and ±0.07° 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 MAX19707 operates on a single 2.7V to 3.3V analog supply and 1.8V to 3.3V digital I/O supply. The MAX19707 is specified for the extended (-40°C to +85°C) temperature range and is available in a 48-pin, thin QFN package. The Selector Guide at the end of the data sheet lists other pin-compatible versions in this AFE family.

Product Detail

The MAX19705–MAX19708 evaluation systems (EV systems) consist of a MAX19705–MAX19708 evaluation kits (EV kits), a companion Maxim command module (CMOD232 or CMODUSB) interface board, and software. Order the complete EV system (see the Ordering Information) for comprehensive evaluation of the MAX19705–MAX19708 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 MAX19705–MAX19708 EV kits are fully assembled and tested circuit boards that contain all the components necessary to evaluate the performance of the MAX19705–MAX19708 analog front-ends (AFEs). The MAX19705–MAX19708 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 (CMOD232 or CMODUSB) allows a PC to use its serial or USB port to emulate an SPI 3-wire interface. Windows® 98/2000/XP-compatible software, which can be downloaded from www.maximintegrated.com, provides a user-friendly interface to exercise the features of the MAX19705–MAX19708. 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 (PMR)
