video data to an NTSC, PAL or
SECAM CVBS or S-video signal. Simultaneously, RGB or bypassed but interpolated
C

-Y-C
B
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 C

B
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.
