IC1905 HDMI-
Receiver VHI-1Q The SiI9025 is a second generation panelLink Cinema receiver that is compatible with
the HDMI 1.1 (High Definition Multimedia interface)specification. The SiI9025 is capa-
ble of receiving and outputting two channel digital audio at up to 192KHz - an excellent
solution for Digital TVs. The features of this IC is as follow.
1) Digital video interface supports video processors:
2) Analog RGB and YPbPr output: 10-bit DAC
3) Digital audio interface supports high-end audio systems: M1
