Detailed Description
In the typical application circuit for a portable DVD
player (Figure 1), the current DACs on a DVD decoder
chip generate video signals. When the internal signal
sources are selected, the MAX9508 filters those signals
and then drives the video connectors through a 75
back termination resistor. When external video sources
are selected, the MAX9508 selects the external com-
posite video signal (EXTCVBSIN), filters, and amplifies
it. The output stages of the amplifiers connected to
COUT, YOUT, and CVBSOUT1 become high imped-
ance. The n-channel switch at CVBSOUT1 turns on,
thereby converting the back termination resistor into an
input termination resistor.
SmartSleep Feature
The SmartSleep feature is activated when the SMARTSLEEP
input is connected to logic high. The SmartSleep feature
provides intelligent power management by selectively
disabling the filters and output amplifiers based on
the presence of video signals or loads attached to the
