ADI recommended input muxing is designed to minimize
crosstalk between signal channels and to obtain the highest
level of signal integrity. Table 9 summarizes how PCB layout
should connect analog video signals to the ADV7183A.
Notes
•
•
•
It is strongly recommended to connect any unused analog
input pins to AGND to act as a shield.
Inputs AIN7 to AIN11 should be connected to AGND in
cases where only six input channels are used. This improves
the quality of the sampling due to better isolation between
the channels.
AIN12 is not under the control of INSEL[3:0]. It can only
be routed to ADC0/ADC1/ADC2 by manual muxing. See
Table 10 for further details.
