GENERAL DESCRIPTION
The SAA7128H; SAA7129H encodes digital CB-Y-CR video data to an NTSC, PAL or SECAM CVBS or S-video signal. Simultaneously, RGB or bypassed but interpolated CB-Y-CR signals are available via three additional DACs.

FEATURES
• Monolithic CMOS 3.3 V device, 5 V I2C-bus optional
• Digital PAL/NTSC/SECAM encoder
• System pixel frequency 13.5 MHz
• 54 MHz double-speed multiplexed D1 interface capable
   of splitting data into two separate channels (encoded
   and baseband)
• Three Digital-to-Analog Converters (DACs) for CVBS
   (CSYNC), VBS (CVBS) and C (CVBS) two times
   oversampled with 10-bit resolution (signals in brackets
   optional)
• Three DACs for RED (CR), GREEN (Y) and BLUE (CB)
   two times oversampled with 9-bit resolution (signals in
   brackets optional)
• Alternatively, an advanced composite sync is available
   on the CVBS output for RGB display centring
• Real-time control of subcarrier
• Cross-colour reduction filter
• Closed captioning encoding and World Standard
   Teletext (WST) and North-American Broadcast Text
   System (NABTS) teletext encoding including sequencer
   and filter
• 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
   I2C-bus
• Fast I2C-bus control port (400 kHz)
• Line 23 Wide Screen Signalling (WSS) encoding
• Video Programming System (VPS) data encoding in
   line 16 (50/625 lines counting)
• Encoder can be master or slave (Continue ...)
