Rev. 02 — 9 May 2005
Product data sheet
1. 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 multistandard 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 multistandard VBI data
slicer and a 27 MHz VBI data bypass.
The pure 3.3 V 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 color of PAL, SECAM and
NTSC signals into ITU-R BT 601 compatible color component values. The SAA7113H
accepts as analog inputs CVBS or S-video (Y/C) from TV or VTR sources. The circuit is
I
2
C-bus controlled.
The integrated high performance multistandard data slicer supports several VBI data
standards:
•
Teletext 625 lines: WST (World Standard Teletext) and CCST (Chinese teletext)
•
Teletext 525 lines: US-WST, NABTS (North-American Broadcast Text System) and
MOJI (Japanese teletext)
•

Time codes (VITC EBU/SMPTE)
High-speed VBI data bypass for Intercast application.
