9-bit video input processor

Product specification

SAA7113H

3 GENERAL DESCRIPTION

The 9-bit video input processor is a combination of a

two-channel analog preprocessing circuit including source

selection, anti-aliasing filter and ADC, an automatic clamp

and gain control, a Clock Generation Circuit (CGC), a

digital multi-standard decoder (PAL BGHI, PAL M, PAL N,

combination PAL N, NTSC M, NTSC-Japan, NTSC N and

SECAM), a brightness, contrast and saturation control

circuit, a multi-standard VBI data slicer and a 27 MHz

VBI data bypass; see Fig.1.

The pure 3.3 V (5 V compatible) CMOS circuit SAA7113H,

analog front-end and digital video decoder, is a highly

integrated circuit for desktop video applications.

The decoder is based on the principle of line-locked clock

decoding and is able to decode the colour of PAL, SECAM

and NTSC signals into CCIR-601 compatible colour

component values. The SAA7113H accepts as analog

inputs CVBS or S-video (Y/C) from TV or VTR sources.

The circuit is I2C-bus controlled.

The integrated high performance multi-standard data

slicer supports several VBI data standards:

• Teletext [WST (World Standard Teletext), CCST

(Chinese teletext)] (625 lines)

• Teletext [US-WST, NABTS (North-American Broadcast

Text System) and MOJI (Japanese teletext)] (525 lines)

• Closed caption [Europe, US (line 21)]

• Wide Screen Signalling (WSS)

• Video Programming Signal (VPS)

• Time codes (VITC EBU/SMPTE)

• HIGH-speed VBI data bypass for intercast application.
