10-Bit, 7.5Msps, Full-Duplex

Analog Front-End

MAX9710

General Description

Features

♦ Dual 10-Bit, 7.5Msps Rx ADC and Dual 10-Bit,

The MAX19710 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,

7.5Msps receive (Rx) ADC; dual 10-bit, 7.5Msps 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 30mW at a 7.5MHz clock frequency.

7.5Msps Tx DAC

♦ Ultra-Low Power

30mW at f_CLK= 7.5MHz, FD Mode

21.3mW at f_CLK= 7.5MHz, Slow Rx Mode

21.9mW at f_CLK= 7.5MHz, 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 = 54.9dB at f_IN= 3.3MHz (Rx ADC)

The Rx ADCs feature 54.8dB SINAD and 79.8dBc SFDR

at 3.3MHz input frequency with a 7.5MHz clock frequen-

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

SFDR = 73.8dBc at f_OUT= 620kHz (Tx DAC)

♦ Three 12-Bit, 1μs Aux-DACs

and accept 1.024V

full-scale signals. Typical I/Q

P-P

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

channel matching is 0.01ꢀ phase and 0.01dB gain.

Data Averaging

The Tx DACs feature 73.8dBc SFDR at f = 620kHz

OUT

♦ Excellent Gain/Phase Match

0.01° Phase, 0.01dB Gain (Rx ADC) at

f_IN= 1.8MHz

and f

= 7.5MHz. 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 0.15ꢀ phase.

♦ Multiplexed Parallel Digital I/O

♦ Serial-Interface Control

♦ Versatile Power-Control Circuits

Shutdown, Standby, Idle, Tx/Rx Disable

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.

(7mm x 7mm x 0.8mm)

Pin Configuration

TOP VIEW

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 (-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.
