Notes
1. Machine model: L = 0.75 H, C = 200 pF and R = 0 .
2. Human body model: equivalent to discharging a 100 pF capacitor through a 1.5 k resistor.DescriptionThe SAA7134HL is a single chip solution to digitize and decode video and sound, and to capture both data streams through the PCI-bus.
Special means of SAA7134HL are incorporated to maintain the synchronization of audio to video. The SAA7134HL offers versatile peripheral interfaces (GPIO), that support various extended applications, e.g. analog audio pass-through for loop back cable to the sound card, or capture of DTV and DVB transport streams, such as Vestigial Side Band (VSB), Orthogonal Frequency Division Multiplexing (OFDM) and Quadrature Amplitude Modulation (QAM) decoded digital television standards (see Fig.1).
