GENERAL DESCRIPTION
The one chip front-end SAA7110; SAA7110A is a digital
multistandard colour decoder (OCF1) on the basis of the
DIG-TV2 system with two integrated Analog-to-Digital
Converters (ADCs), a Clock Generation Circuit (CGC) and
Brightness Contrast Saturation (BCS) control.
The CMOS circuit SAA7110; SAA7110A, 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. It operates
square-pixel frequencies to achieve correct aspect ratio.
Monitor controls are provided to ensure best display. The
circuit is I
