V
DD
Analog Supply Voltage. Supply range from 2.7V to 3.3V. Bypass V
DD
to GND with a combination of
a 2.2µF capacitor in parallel with a 0.1µF capacitor.
3 IAP Channel-IA Positive Analog Input. For single-ended operation, connect signal source to IAP.
4 IAN Channel-IA Negative Analog Input. For single-ended operation, connect IAN to COM.
5, 7, 12, 32, 42
GND Analog Ground. Connect all GND pins to ground plane.
6 CLK Conversion Clock Input. Clock signal for both receive ADCs and transmit DACs.
9 QAN Channel-QA Negative Analog Input. For single-ended operation, connect QAN to COM.
