4 / 80 page 1999 Jul 01 4 Philips Semiconductors Product specification 9-bit video input processor 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. 4 QUICK REFERENCE DATA 5 ORDERING INFORMATION SYMBOL PARAMETER MIN.
