Description
The MAX19713 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,
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 typical operating power in
FD mode is 91.8mW at a 45MHz clock frequency.
The Rx ADCs feature 54dB SINAD and 72.2dBc SFDR at
5.5MHz input frequency with a 45MHz clock frequency.
The analog I/Q input amplifiers are fully differential and
accept 1.024VP-P full-scale signals. Typical I/Q channel
matching is ±0.03 phase and ±0.02dB gain.
The Tx DACs feature 70.3dBc SFDR at fOUT = 2.2MHz
and fCLK = 45MHz. The analog I/Q full-scale output voltage
range is ±400mV differential. The output DC common-mode voltage is selectable from 0.71V to 1.06V. The
I/Q channel offset is adjustable to optimize radio lineup
sideband/carrier suppression. Typical I/Q channel
matching is ±0.01dB gain and ±0.05° 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 applications.
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 MAX19713 operates on a single 2.7V to 3.3V analog
supply and 1.8V to 3.3V digital I/O supply. The
MAX19713 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.
