1. General description
The SAA7131E combines a digital global standard low-IF demodulator for analog TV with
a PCI audio and video decoder.
The IF demodulator is an alignment-free digital multistandard vision and sound low-IF
signal PLL demodulator for positive and negative video modulation. It can be used
worldwide for M/N, B/G/H, I, D/K and L/L’ standards. The IF demodulator is especially
suited for the application with the TV Silicon Tuner TDA18271, TDA8275A or equivalent
IC.
The PCI audio and video broadcast decoder is a highly integrated, low-cost and solid
foundation for TV capture in the PC, for analog TV and digital video broadcast (DTV and
DVB). The various multimedia data types are transported over the PCI-bus by bus
master-write, to best exploit the streaming capabilities of a modern host based system;
see Figure 1.
