Product data sheet
1. General description
The SAA7128H; SAA7129H encodes digital CR-Y-CB video data to an NTSC, PAL or SECAM CVBS or S-video signal. Simultaneously, RGB or bypassed but interpolated CR-Y-CB signals are available via three additional DACs. The circuit at a 54 MHz multiplexed digital D1 input port accepts two ITU-R BT.656 patible CR-Y-CB 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 clock edge and the other at the falling clock edge.
It includes a sync/clock generator and on-chip DACs.
