1. General description
The SAA7142HL is a combination of two stand-alone multi-standard video decoders.
The SAA7142HL is a pure 3.3 V (5 V tolerant inputs and I/Os) Complementary
Metal-Oxide Semiconductor (CMOS) circuit and a highly integrated circuit for video
surveillance applications. Both video decoders are based on the principle of line-locked
clock decoding and are able to decode the color of Phase Alternating Line (PAL),
Sequentiel Couleur avec Memoire (SECAM) and National Television Standards
Committee (NTSC) signals into “ITU-R BT 601” compatible color component values.
The SAA7142HL accepts as analog inputs in total four Color Video Blanking Signal
(CVBS) sources from TV or VTR (two selectable CVBS sources for each decoder).
Each of the video decoders (A and B) contains an analog preprocessing circuit including
source selection for two CVBS sources, anti-aliasing filter and Analog-to-Digital Converter
(ADC), an automatic clamp and gain control, a Clock Generation Circuit (CGC), a digital
multi-standard decoder (PAL, NTSC and SECAM), a Brightness Contrast Saturation
(BCS) control circuit, a multi-standard text slicer (see
Blanking Interval (VBI) data bypass.
The integrated high-performance multi-standard data slicer supports several VBI data
standards:
The circuit is I
