TMC2491A Datasheet Multistandard Digital Video Encoder

Manufacturer: Fairchild (now onsemi)

Overview: TMC2490A/TMC2491A Multistandard Digital Video Encoder .fairchildsemi.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The TMC2490(1)A video encoder converts digital ponent video (in 8-bit parallel CCIR-601/656 or ANSI/SMPTE 125M format) into a standard analog baseband television (NTSC, NTSC-EIA, and all PAL standards) signal with a modulated color subcarrier.

Both posite (single lead) and S-Video (separate chroma and luma) formats are active simultaneously at all three analog outputs.

Each video output generates a standard video signal capable of driving a singlyor doubly-terminated 75 Ohm load.
