MAX9713

General Description

Features

♦ Dual 10-Bit, 45Msps Rx ADC and Dual 10-Bit,

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.

45Msps Tx DAC

♦ Ultra-Low Power

91.8mW at f_CLK= 45MHz, FD Mode

79.2mW at f_CLK= 45MHz, Slow Rx Mode

49.5mW at f_CLK= 45MHz, Slow Tx Mode

Low-Current Standby and Shutdown Modes

♦ Programmable Tx DAC Common-Mode DC Level

and I/Q Offset Trim

♦ Excellent Dynamic Performance

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

full-scale signals. Typical I/Q channel

matching is 0.03 phase and 0.02dB gain.

SNR = 54.1dB at f_IN= 5.5MHz (Rx ADC)

SFDR = 70.3dBc at f_OUT= 2.2MHz (Tx DAC)

accept 1.024V

♦ Three 12-Bit, 1µs Aux-DACs

The Tx DACs feature 70.3dBc SFDR at f

= 2.2MHz

♦ 10-Bit, 333ksps Aux-ADC with 4:1 Input Mux and

OUT

and f

= 45MHz. The analog I/Q full-scale output volt-

CLK

Data Averaging

age range is 400mV differential. The output DC com-

mon-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 0.05ꢀ phase.

♦ Excellent Gain/Phase Match

0.03° Phase, 0.02dB Gain (Rx ADC) at

f_IN= 5.5MHz

♦ Multiplexed Parallel Digital I/O

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 applica-

tions. 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.

♦ Serial-Interface Control

♦ Versatile Power-Control Circuits

Shutdown, Standby, Idle, Tx/Rx Disable

♦ Miniature 56-Pin Thin QFN Package

(7mm x 7mm x 0.8mm)

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 (-40ꢀC to

+85ꢀC) 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.
