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.
