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. 2.
