APPLICATION CIRCUIT EXAMPLE (YCbCr 16-bit input mode)
Sample of Analog Output Circuit
Note: The filters shown above are samples to be referenced.
5 V or 3.3 V
Controller
Overlay
Filters to be used can be selected by the user.
The analog output circuit shown above is a sample when a destination connected to is
terminated with 75 W load. If the connected destination is not terminated or is drived with
37.5 W load, the analog output circuit should use 75 W resistors.
If the YA, CA and CVBSO pins are terminated with 37.5 W load, an operational amplifier
is not used.
