GENERAL DESCRIPTION
SAA7111A
The Enhanced Video Input Processor (EVIP) 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, NTSC M,
NTSC-Japan NTSC N and SECAM), a
brightness/contrast/saturation control circuit, a colour
space matrix (see Fig.1) and a 27 MHz VBI-data bypass.
The pure 3.3 V CMOS circuit SAA7111A, 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 SAA7111A accepts as analog inputs CVBS
or S-video (Y/C) from TV or VTR sources. The circuit is
I

C-bus controlled. The SAA7111A then supports several
text features as Line 21 data slicing and a high-speed VBI
data bypass for Intercast.
