tings in situations where cable length is known. For example,
if 25 meter cable length is required, Pericom's solution can be
adjusted to 16dB EQ to accept 25 meter cable length.
Using Pericom's patent-pending Rx termination detection circuit,
PI3HDMI101-B can automatically disable its own input 50-Ohm
termination when no 50-Ohm termination is detected in the
HDMI Rx chipset. If a switch is used between the PI3HDMI101-B
and the HDMI Rx, our part can detect the 50-Ohm termination
in the switch to determine if our input should be off or on.

TMDS Receiver Block
Each high speed data and clock input has integrated equalization that can eliminate deterministic jitter caused by input cables.
All activity can be configured using pin strapping. The Rx block is designed to receive all relevant signals directly from the HDMI
connector without any additional circuitry, 3 High speed TMDS data, 1 pixel clock, and DDC signals. TMDS channels have the fol-
lowing termination scheme for Rx Sense support. The switching between 50-Ohm termination vs. 250K-Ohm termination is done
automatically. The PI3HDMI101-B monitors the 50-Ohm termination in the Rx chipset behind our part, and when this 50-Ohm
termination is not present, we disable our 50-Ohm termination at our input.
