Notes: 1. Absolute maximum ratings are limiting values applied individually, while all other parameters are within specified operating conditions. Functional operation under any of these conditions is NOT implied.
2. Applied voltage must be current limited to specified range, and measured with respect to VSS.
3. Forcing voltage must be limited to a specified range.
4. Current is specified as conventional current, flowing into the device.

The KS0123 multi-standard video encoder converts CCIR 656 8-bit multiplexed digital component video into analog baseband signals. It outputs composite video (CVBS) and S-Video simultaneously at three analog output pins.

The encoder implements Macrovision revision 6.0 antitaping scheme. Additionally,KS0123 contains a color subcarrier genlock to support analog/digital video splicing.

The video outputs conform to either SMPTE 170M (NTSC) or CCIR 624 (PAL) standards.
