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 (±0.2V) 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
Figure 1 displays a simplified diagram of the Rx ADC
input track-and-hold (T/H) circuitry. Both ADC inputs
(IAP, QAP, IAN, and QAN) can be driven either differen-
tially or single-ended. Match the impedance of IAP and
IAN, as well as QAP and QAN, and set the input signal
common-mode voltage within the VDD /2 (±200mV)
Rx ADC range for optimum performance.
