General Description
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.
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
and accept 1.024VP-P full-scale signals. Typical I/Q
channel matching is ±0.01° phase and ±0.01dB gain.
The Tx DACs feature 73.8dBc SFDR at fOUT = 620kHz
and fCLK = 7.5MHz. The analog I-Q full-scale output volt-
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 ±0.15° 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 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 (-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.
