Figure 1. Rx ADC Internal T/H Circuits
The MAX19712 integrates three 12-bit auxiliary DACs
(aux-DACs) and a 10-bit, 333ksps auxiliary ADC (aux-
ADC) with 4:1 input multiplexer. The aux-DAC channels
feature 1s settling time for fast AGC, VGA, and AFC
level setting. The aux-ADC features data averaging to
reduce processor overhead and a selectable clock-
divider to program the conversion rate.
The MAX19712 includes a 3-wire serial interface to con-
trol operating modes and power management. The seri-
al interface is SPI and MICROWIRE compatible.
The MAX19712 serial interface selects shutdown, idle,
standby, FD, transmit (Tx), and receive (Rx) modes, as
well as controls aux-DAC and aux-ADC channels.
The MAX19712 features two independent, high-speed,
10-bit buses for the Rx ADC and Tx DAC, which allow
full-duplex (FD) operation for frequency-division duplex
applications. Each bus can be disabled to optimize
power management through the 3-wire interface. The
MAX19712 operates from a single 2.7V to 3.3V analog
supply and a 1.8V to 3.3V digital supply.
Dual 10-Bit Rx ADC
The ADC uses a seven-stage, fully differential, pipelined
architecture that allows for high-speed conversion while
minimizing power consumption. Samples taken at the
inputs move progressively through the pipeline stages
every half clock cycle. Including the delay through the
output latch, the total clock-cycle latency is 5 clock
cycles for channel IA and 5.5 clock cycles for channel
QA. The ADC full-scale analog input range is ±VREF
with a VDD / 2 (±0.8V) common-mode input range. VREF
is the difference between VREFP and VREFN. See the
Reference Configurations section for details.
Input Track-and-Hold (T/H) Circuits

input track-and-hold (T/H) circuitry. Both ADC inputs
