                  SAA7128H; SAA7129H
                  Digital video encoder
                  Rev. 03 -- 9 December 2004                             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 compatible 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.
