10-Bit, 45Msps, Ultra-Low-Power

Analog Front-End

General Description

Features

The MAX19707 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, 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 typ-

ical operating power in Tx-Rx FAST mode is 84.6mW at

a 45MHz clock frequency.

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

45Msps Tx DAC

♦ Ultra-Low Power

84.6mW at f_CLK= 45MHz, Fast Mode

77.1mW at f_CLK= 45MHz, Slow Mode

Low-Current Standby and Shutdown Modes

♦ Programmable Tx DAC Common-Mode DC Level

and I/Q Offset Trim

♦ Excellent Dynamic Performance

SNR = 54.2dB at f_IN= 5.5MHz (Rx ADC)

SFDR = 73.2dBc at f_OUT= 2.2MHz (Tx DAC)

The Rx ADCs feature 54.2dB SNR and 71.2dBc SFDR

at f_IN= 5.5MHz and f

= 45MHz. The analog I/Q

CLK

input amplifiers are fully differential and accept

♦ Three 12-Bit, 1µs Aux-DACs

1.024V full-scale signals. Typical I/Q channel match-

P-P

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

ing is 0.03ꢀ phase and 0.01dB gain.

Data Averaging

The Tx DACs feature 73.2dBc SFDR at f

= 2.2MHz

OUT

♦ Excellent Gain/Phase Match

0.03ꢀ Phase, 0.01dB Gain (Rx ADC) at

f_IN= 5.5MHz

and f

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

CLK

age 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 0.07ꢀ phase.

♦ Multiplexed Parallel Digital I/O

♦ Serial-Interface Control

♦ Versatile Power-Control Circuits

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.

Shutdown, Standby, Idle, Tx/Rx Disable

♦ Miniature 48-Pin Thin QFN Package

(7mm x 7mm x 0.8mm)

Pin Configuration

The MAX19707 operates on a single 2.7V to 3.3V ana-

log supply and 1.8V to 3.3V digital I/O supply. The

MAX19707 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.
