CVBS Video Filter Amplifier with SmartSleep
and Bidirectional Video Support
Set the INT/EXT control input low for internal mode. The
MAX9513 processes video signals from an internal
source such as a DVD chip (Figure 7). The 2:1 multi-
plexer selects the video signal on CVBSIN. The
EXTCVBSIN video signal is ignored.
