General Description
The MAX19711 is an ultra-low-power, highly integrated
mixed-signal analog front-end (AFE) ideal for CDMA
communication applications operating in full-duplex
(FD) mode. Optimized for high dynamic performance
and ultra-low power, the device integrates a dual 10-bit,
11Msps receive (Rx) ADC; dual 10-bit, 11Msps transmit
(Tx) DAC with CDMA baseband filters; three fast-settling
12-bit aux-DAC channels for ancillary RF front-end con-
trol; and a 10-bit, 333ksps housekeeping aux-ADC. The
typical operating power in FD mode is 37.5mW/42.7mW
at a 4.915MHz/11MHz clock frequency.
The Rx ADCs feature 54.8dB SNR and 74.2dBc SFDR at
1.875MHz input frequency with an 11MHz clock frequen-
cy. The analog I/Q input amplifiers are fully differential
and accept 1.024VP-P full-scale signals. Typical I/Q
channel matching is ±0.01° phase and ±0.01dB gain.
The Tx DACs with CDMA lowpass filters feature -3dB
cutoff frequency of 1.3MHz and > 64dBc stopband
rejection at fIMAGE = 4.285MHz at fCLK = 4.915MHz. The
analog I-Q full-scale output voltage range is selectable at
±410mV or ±500mV differential. The output DC common-
mode voltage is selectable from 0.86V to 1.36V. The I/Q
channel offset is adjustable to optimize radio lineup side-
band/carrier suppression. Typical I-Q channel matching
is ±0.03dB gain and ±0.07° phase.
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.
The MAX19711 operates on a single 2.7V to 3.3V analog
supply and 1.8V to 3.3V digital I/O supply. The
MAX19711 is specified for the extended (-40°C to
+85°C) 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.
