DESCRIPTION
2
The SAA7128AH; SAA7129AH encodes digital C
video data to an NTSC, PAL or SECAM CVBS or S-video
signal. Simultaneously, RGB or bypassed but interpolated
C
Through a 54 MHz multiplexed digital D1 input port, the
circuit accepts two ITU-R BT.656 compatible C
data streams with 720 active pixels per line in
4 : 2 : 2 multiplexed formats. For example, MPEG
decoded data with overlay and MPEG decoded data
without overlay, where one data stream is latched at the
rising, the other one is latched at the falling clock edge.
It includes a sync/clock generator and on-chip DACs.
