10-Bit, 22Msps, Full-Duplex

Analog Front-End

MAX9712

General Description

Features

♦ Dual 10-Bit, 22Msps Rx ADC and Dual 10-Bit,

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.

22Msps Tx DAC

♦ Ultra-Low Power

50.4mW at f_CLK= 22MHz, FD Mode

39.9mW at f_CLK= 22MHz, Slow Rx Mode

33.9mW at f_CLK= 22MHz, Slow Tx Mode

Low-Current Standby and Shutdown Modes

♦ Programmable Tx DAC Common-Mode DC Level

and I/Q Offset Trim

♦ Excellent Dynamic Performance

SNR = 54.8dB at f_IN= 5.5MHz (Rx ADC)

The Rx ADCs feature 54.7dB SINAD and 75.6dBc SFDR

at 5.5MHz input frequency with a 22MHz clock frequen-

cy. The analog I/Q input amplifiers are fully differential

SFDR = 72.9dBc at f_OUT= 2.2MHz (Tx DAC)

♦ Three 12-Bit, 1μs Aux-DACs

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

and accept 1.024V

full-scale signals. Typical I/Q

P-P

Data Averaging

channel matching is 0.01ꢀ phase and 0.01dB gain.

♦ Excellent Gain/Phase Match

0.01° Phase, 0.01dB Gain (Rx ADC) at

f_IN= 5.5MHz

The Tx DACs feature 72.9dBc SFDR at f = 2.2MHz

OUT

and f

= 22MHz. The analog I-Q full-scale output volt-

CLK

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

mon-mode voltage is from 0.89V to 1.36V. The I/Q

channel offset is adjustable to optimize radio lineup side-

band/carrier suppression. Typical I-Q channel matching

is 0.01dB gain and 0.1ꢀ phase.

♦ Multiplexed Parallel Digital I/O

♦ Serial-Interface Control

♦ Versatile Power-Control Circuits

Shutdown, Standby, Idle, Tx/Rx Disable

♦ Miniature 56-Pin Thin QFN Package

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.

Pin Configuration

TOP VIEW

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 (-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.
