SAA7144HL Quadruple video input processor Rev. 01 — 21 April 2005 www.DataSheet4U.com Product data sheet 1. General description The SAA7144HL is a combination of four stand alone multistandard video decoders. The SAA7144HL is a pure 3.3 V (5 V tolerant inputs and I/Os) CMOS circuit and a highly integrated circuit for video surveillance applications. All four video decoders are based on the principle of line-locked clock decoding and are able to decode the color of PAL, SECAM and NTSC signals into “CCIR 601” compatible color component values. The SAA7144HL accepts as analog inputs in total eight CVBS sources from TV or VTR (two selectable CVBS sources for each of the four decoders).
