PI3HDMI1310-A

HDMIâ¢ Switch with non-blocking EQ Circuitry

BLOCK DIAGRAM EXPLANATION

DDC Switch Block

Passive NMOS based 3:1 mux for DDC channels from each HDMI/DVI input connector. This section can remain active even when

3.3V supply is gone, as long as 5.0V from TMDS connector is connected to the PI3HDMI1310-A IC.

3:1 High speed Differential Channel Block

4-differential channels per port. 3 channels are targeted for high speed data channels (250Mbps to 3.4Gbps) and 1 channel is

targeted for high speed clock signal (25MHz to 340MHz).

HPD Control Channels Block

Drives each HPD channels through the input pin, HPD_Sink.

This signal will need to drive external pull-down transistor circuit before connecting to the HDMI/DVI connector. The external

pull down circuit will look like the following:
