Product data sheet
Video is digitized and decoded to YUV. The digital streams are pumped via DMA into the
PCI memory space.
The SAA7130HL incorporates the means for legacy analog audio signal routing. The
analog audio input signal is fed via an analog audio loopback cable into the line-in of a
legacy sound card. An external audio signal, that would have otherwise connected directly
to the sound card, is now routed through the SAA7130HL. This analog pass-through is
enabled as default by a system reset, i.e. without any driver involvement and before
system setup.
During the power-up procedure, the SAA7130HL will investigate the on-board EEPROM
to load the board-specific system vendor ID and board version ID into the related places
of the PCI configuration space. The board vendor can store other board-specific data in
the EEPROM that is accessible via the I

The single-conversion tuner TD1316 provides two dedicated IF signals for the analog
IF-PLL (TDA9886) and the digital IF-PLL (TDA9889). The CVBS (video) and AUD (audio,
mono) output signals of the analog IF-PLL can be routed to one of the video inputs and
