video decoder
Rev. 02 — 13 August 2007
Product short data sheet
1. General description
The SAA7162E is a dual channel multistandard audio and video TV decoder with digital
IF demodulator and PCI Express interface. It provides 10-bit ADC, enhanced PAL/NTSC
comb filtering, a versatile VBI data processing, more sophisticated scaling algorithms,
support of high definition component video, picture improvement processing, more
robustness with VCR type signals, increased audio functionality like SPDIF input/output,
I²S-bus input/output and an integrated audio sample rate converter from 32 kHz to
44.1 kHz or 48 kHz.
The SAA7162E is a highly integrated circuit for e.g. TV insertion inside PC systems. The
multistandard TV decoder covered all video color standards like PAL, NTSC and SECAM
and sound standards like dual FM, NICAM, BTSC and EIAJ. Additional to the TV decoder
function a digital IF demodulator, an FM radio decoder, standard interfaces for digital
video and audio, remote control receiver and transmission processing and a high-speed
programming port allows high integrated system solutions for multimedia application.
