INPUT CONFIGURATION
Table 10. ADV7180 LQFP-64 INSEL[3:0]
There are two key steps for configuring the ADV7180 to
correctly decode the input video.

1. Use INSEL[3:0] to configure routing and format decoding
(CVBS, Y/C, or YPrPb). For the ADV7180 LQFP-64, see
Table 10. For ADV7180 LFCSP-40, see Table 11.

2. If the input requirements are not met using the INSEL[3:0]
options, the analog input muxing section must be

configured manually to correctly route the video from the
analog input pins to the ADC. The standard definition
processor block, which decodes the digital data, should be
configured to process either CVBS, Y/C, or YPrPb format.
This is performed by INSEL[3:0] selection.

The INSEL bits allow the user to select the input format. They
also configure the standard definition processor core to process
composite (CVBS), S-video (Y/C), or component (YPrPb)
format.

INSEL[3:0] has predefined analog input routing schemes that
do not require manual mux programming (see Table 10 and
Table 11). This allows the user to route the various video signal
types to the decoder and select them using INSEL[3:0] only.
The added benefit is that if, for example, CVBS input is selected,
the remaining channels are powered down.
