GENERAL DESCRIPTION

The SAA7182A; SAA7183A encodes digital YUV video data to an NTSC, PAL, SECAM CVBS or S-Video signal and also RGB.

Optionally, the YUV to RGB dematrix can be by-passed providing the digital-to-analog converted Cb, Y, Cr signals instead of RGB.

FEATURES

• Monolithic CMOS 3.3 V device with 5 V input stages

• Digital PAL/NTSC/SECAM encoder

• System pixel frequency 13.5 MHz

• Accepts MPEG decoded data on 8-bit wide input port. Input data format Cb, Y, Cr etc. “(CCIR 656)” or Y and Cb, Cr on 16 lines

• Three DACs for CVBS, Y and C operating at 27 MHz with 10 bit resolution

• Three DACs for RGB operating at 27 MHz with 9 bit resolution, RGB sync on CVBS and Y

• Analog multiplexing between internal RGB and external RGB on-chip

• CVBS, Y, C and RGB output simultaneously

• Closed captioning and teletext encoding including sequencer and filter

• Line 23 wide screen signalling encoding

• On-chip Cr, Y, Cb to RGB dematrix, including gain adjustment for Y and Cr, Cb, optionally to be by-passed for Cr, Y, Cb output on RGB DACs

• 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)

• Overlay with Look-Up Tables (LUTs) 8 × 3 bytes

• Macrovision Pay-per-View copy protection system as option, also used for RGB output.

This applies to SAA7183A only. The device is protected by USA patent numbers 4631603, 4577216 and 4819098 and other intellectual property rights.
