ADI Recommended Input Muxing
A maximum of 12 CVBS inputs can be connected and decoded
by the ADV7188. As seen in Figure 5, this means the sources
must be connected to adjacent pins on the IC. This calls for a
careful design of the PCB layout, for example, ground shielding
between all signals routed through tracks that are physically
close together.

SDM_SEL[1:0], S-Video and CVBS Autodetect Mode Select,
Address 0x69 [1:0]
The SDM_SEL bits decide on input routing and whether
INSEL[3:0] is used to govern I/P routing decisions.
The CVBS/YC autodetection feature is enabled using
SDM_SEL = 11.

INSEL[3:0] Input Selection, Address 0x00 [3:0]
The INSEL bits allow the user to select an input channel and the
input format. Depending on the PCB connections, only a subset
of the INSEL modes are valid. The INSEL[3:0] not only switches
the analog input muxing, it also configures ADV7188 to process
CVBS (Comp), S-Video (Y/C), or component (YPbPr) format.
ADI-recommended input muxing is designed to minimize
crosstalk between signal channels and to obtain the highest
level of signal integrity. Table 10 summarizes how the PCB
layout should connect analog video signals to the ADV7188.
It is strongly recommended to connect any unused analog input
pins to AGND to act as a shield.
Connect inputs AIN7 to AIN11 to AGND when 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 be routed
to ADC0/ADC1/ADC2 only by manual muxing. See Table 11
for details.
