KS0123 Data Sheet
DIGITAL VIDEO ENCODER
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 anti-
taping scheme. Additionally, it 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.
