10-Bit, 45Msps, Ultra-Low-Power
Analog Front-End
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 ±V
with a V

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 differ-
entially 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 Rx ADC range
