10-Bit, 7.5Msps, Ultra-Low-Power

Analog Front-End

General Description

Features

The MAX19705 is an ultra-low-power, mixed-signal ana-

log front-end (AFE) designed for power-sensitive com-

munication equipment. Optimized for high dynamic

performance at 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 typ-

ical operating power in Tx-Rx FAST mode is 28.2mW at

a 7.5MHz clock frequency.

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

7.5Msps Tx DAC

♦ Ultra-Low Power

28.2mW at f_CLK= 7.5MHz, Fast Mode

21mW at f_CLK= 7.5MHz, Slow 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 55.1dB SNR and 73.4dBc SFDR at

a 1.875MHz input frequency with a 7.5MHz clock fre-

quency. The analog I/Q input amplifiers are fully differen-

SNR = 55.1dB at f_IN= 1.875MHz (Rx ADC)

SFDR = 77.2dBc at f_OUT= 620kHz (Tx DAC)

♦ Three 12-Bit, 1µs Aux-DACs

tial and accept 1.024V

full-scale signals. Typical I/Q

P-P

channel matching is 0.01ꢀ phase and 0.02dB gain.

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

Data Averaging

The Tx DACs feature 77.2dBc SFDR at f = 620kHz

OUT

and f

= 7.5MHz. The analog I/Q full-scale output

CLK

♦ Excellent Gain/Phase Match

voltage is 400mV differential. The Tx DAC common-

mode DC level is programmable from 0.9V to 1.35V.

The I/Q channel offset is adjustable. The typical I/Q

channel matching is 0.03dB gain and 0.08ꢀ phase.

0.01ꢀ Phase, 0.02dB Gain (Rx ADC) at

_IN= 1.875MHz

♦ Multiplexed Parallel Digital I/O

♦ Serial-Interface Control

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.

♦ Versatile Power-Control Circuits

Shutdown, Standby, Idle, Tx/Rx Disable

♦ Miniature 48-Pin Thin QFN Package

(7mm x 7mm x 0.8mm)

The MAX19705 operates on a single +2.7V to +3.3V

analog supply and +1.8V to +3.3V digital I/O supply.

The MAX19705 is specified for the extended (-40ꢀC to

+85ꢀC) 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.
