ML6461

The ML6461 is a multi-standard CCIR656 (4:2:2) video (input) composite and S-video (outputs) encoder for NTSC systems. It is designed to provide a low cost, single-chip output interface for a variety of video applications including set-top decoders, DVD players, and other YCrCb to Y/C equipment.

The ML6461 accepts 8-bit YCrCb video in either CCIR656 or Square Pixel format and generates analog Y, C and CV waveforms complete with Closed Caption encoding.

The ML6461 includes output analog reconstruction filters, phase equalizer, and 6dB (2X gain) drivers. Gain scaling, sync, and Y+C mixing are performed at the output of the relevant 10-bit DAC, eliminating the gain mapping stages that require additional DAC bits. The result is Y SNR and granularity remain precisely the same as the source.

The ML6461 supports both master and slave timing operations. S-Video and multiple composite signals can be driven simultaneously into 75 loads.
