Description
The SAA7120; SAA7121 encodes digital YUV video data to an NTSC or PAL CVBS or S-Video signal.
The circuit accepts CCIR compatible YUV data with 720 active pixels per line in 4 : 2 : 2 multiplexed formats, for example MPEG decoded data.
It includes a sync/clock generator and on-chip DACs.
Features
- Monolithic CMOS 3.3 V (5 V) device.
- Digital PAL/NTSC encoder.
- System pixel frequency 13.5 MHz.
- Accepts MPEG decoded data on 8-bit wide input port; input data format Cb-Y-Cr (CCIR 656), SAV and EAV.
- Three DACs for Y, C and CVBS, two times oversampled with 10 bit resolution.
- Real time control of subcarrier.
- Cross colour reduction filter.
- Closed captioning encoding and WST- and NABTS-Teletext encoding including sequencer and f.
