SAA7127规格书详情
GENERAL DESCRIPTION
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-CRsignals are available via three additional
Digital-to-Analog Converters (DACs).
FEATURES
• Monolithic CMOS 3.3 V device, 5 V I2C-bus optionally
• Digital PAL/NTSC 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)
• 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.
• 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 the 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 (CCIR line count)
• Encoder can be master or slave
• Programmable horizontal and vertical input synchronization phase
• Programmable horizontal sync output phase
• Internal Colour Bar Generator (CBG)
