Monitor Out Circuit

Figure 5-5shows that the Monitor Output signal source is limited to an NTSC source, or the DM Module. The NTSC Y and C signals from the 3DYC Comb Filter, are directed back to IC2L00. IC2L00 directs the sig- nals to the monitor Inputs of IC2K00. IC2K00 selects

the signal from IC2L00 or the DM signal input at pins 24 and 26 of IC2K00.

If the signal source is from a Component Input, the DTV Input, VGA Input or MLINK Input, no signal is avail- able at the Monitor Outputs.
