SAA7127H

INTEGRATED CIRCUITS DATA SHEET SAA7126H; SAA7127H Digital video encoder Product specification File under Integrated Circuits, IC22 1999 May 31 Philips Semiconductors Product specification Digital video encoder 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 P...
