General Description
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.
The Rx ADCs feature 54.2dB SNR and 71.2dBc SFDR
at f
IN
= 5.5MHz and f
CLK
= 45MHz. The analog I/Q
input amplifiers are fully differential and accept
1.024V
P-P
full-scale signals. Typical I/Q channel match-
ing is ±0.03° phase and ±0.01dB gain.
The Tx DACs feature 73.2dBc SFDR at f
OUT
= 2.2MHz
and f
CLK
= 45MHz. The analog I/Q full-scale output volt-
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 ±0.07° phase.
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.
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 (-40°C to
+85°C) temperature range and is available in a 48-pin,
thin QFN package. The
Selector Guid
e at the end of the
data sheet lists other pin-compatible versions in this
AFE family.
