SAA7120H; SAA7121H

General description

The SAA7120H; SAA7121H encodes digital YUV video data to an NTSC or PAL CVBS or S-video signal. The circuit accepts CCIR compatible YUV data with 720 active pixels per line in 4 : 2 : 2 multiplexed formats, for example MPEG decoded data. It includes a sync/clock generator and on-chip DACs.

Features

• Monolithic CMOS 3.3 V device
• Digital PAL/NTSC encoder
• System pixel frequency 13.5 MHz
• Accepts MPEG decoded data on 8-bit wide input port; input data format C_B-Y-C_R (CCIR 656)
• Three Digital-to-Analog Converters (DACs) for Y, C and CVBS two times oversampled with 10-bit resolution
• 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
• Line 23 Wide Screen Signalling (WSS) encoding
• Fast I²C-bus control port (400 kHz)
• Encoder can be master or slave
• Programmable horizontal and vertical input synchronization phase
• Programmable horizontal sync output phase
• Internal Colour Bar Generator (CBG)
• 2 x 2 bytes in lines 20 (NTSC) for copy guard management system can be loaded via I²C-bus
• Down mode of DACs
• Controlled rise/fall times of synchronization and blanking output signals
