Information as of 2000-08-23
SAA7126H; SAA7127H; Digital video encoder
The SAA7126H; SAA7127H encodes digital Cb-Y-Cr video data to an NTSC or PAL CVBS or S-video signal. Simultaneously, RGB or
bypassed but interpolated Cb-Y-Cr signals are available via three additional Digital-to-Analog Converters (DACs). The circuit at a 54 MHz
multiplexed digital D1 input port accepts two CCIR compatible Cb-Y-Cr data streams with 720 active pixels per line in 4 :2 :2multiplexed
formats, for example MPEG decoded data with overlay and MPEG decoded data without overlay, whereas one data stream is latched at
the rising, the other one at the falling clock edge.
It includes a sync/clock generator and on-chip DACs.
l
Monolithic CMOS 3.3 V device, 5 V IC-bus optionally
l
Digital PAL/NTSC encoder
l
System pixel frequency 13.5 MHz
l
54 MHz double-speed multiplexed D1 interface capable of splitting data into two separate channels (encoded and baseband)
l
Four Digital-to-Analog Converters (DACs) for CVBS (CSYNC, VBS), RED (Cr, C), GREEN (Y, VBS) and BLUE (Cb, CVBS) two
times oversampled (signals in parenthesis are optionally). RED (Cr), GREEN (Y) and BLUE (Cb) signal outputs with 9-bit resolution,
whereas all other signal outputs have 10-bit resolution; CSYNC is an advanced composite sync on the CVBS output for RGB display
centring.
l
Real-time control of subcarrier
l
Cross-colour reduction filter
l
Closed captioning encoding and World Standard Teletext (WST) and North-American Broadcast Text System (NABTS) teletext
encoding including sequencer and filter
l
Copy Generation Management System (CGMS) encoding (CGMS described by standard CPR-1204 of EIAJ); 20 bits in lines 20/283
(NTSC) can be loaded via the IC-bus
l
Fast IC-bus control port (400 kHz)
