LCD TV architecture, showing usage of Pericom analog switch, HDMI switch and video switch products:
- Traditional LCD TV design used external TV decoder, ADC and TMDS receiver
- PI5A4624 provides two CVBS (Composite) signal switching from TV Tuner and CVBS input port
- PI3V314 provides analog RGB and Component YpbPr video signal 3-channel 4:1 switching
- PI3HDMI412 provides DVI/HDMI 4 channels 4:2 differential signal switching
- PI3V514 can connect up to 4 external video components by switching Horizontal and Vertical synchronous signals
- Pericom's PI3HDMI412 is guaranteed to provide the highest resolution of 1080p required by the HDMI standard. The switch operating at 1.65Gbps rate with the TMDS signal processing achieves it.
- Combination of PI3HDMI412 and PI3V312 can be used to provide complete switching function for HDMI signals. This also includes the EDID signals.
- PI3HDMI412 is the world's first HDMI signal switch
- In addition to the HDMI signal switch, Pericom is also developing active HDMI switch, which will have the capability to drive signals with three different drive capabilities
