Description
Pericom Semiconductor’s PI3HDMI101-B 1:1 active ReDriver™
circuit is targeted for high-resolution video networks that are
based on DVI/HDMI™ standards and TMDS signal processing.
The PI3HDMI101-B is an active ReDriver with Hi-Z outputs.
The device receives differential signals from selected video com-
ponents and drives the video display unit. This solution also
provides a unique advanced pre-emphasis technique to increase
rise and fall times which are reduced during transmission across
long distances.
Each complete HDMI/DVI channel also has slower speed, side
band signals, that are required to be switched. Pericom’s solu-
tion provides a complete solution by integrating the side band
buffer together with the high speed buffer in a single solution.
Using Equalization at the input of each of the high speed chan-
nels, Pericom can successfully eliminate deterministic jitter
caused by long cables from the source to the sink. The elimina-
tion of the deterministic jitter allows the user to use much longer
cables (up to 25 meters).
The maximum DVI/HDMI Bandwidth of 2.5 Gbps provides 36-
bit DeepColor™ support, which is offered by HDMI revision 1.3.
The PI3HDMI101-B also provides enhanced robust ESD/EOS
protection of 8kV, which is required by many consumer video
networks today.
The Optimized Equalization provides the user a single optimal
setting that can provide HDMI compliance for all cable lengths: 1
meter to 20 meters and color depths of 8bit/ch, or 12bit/ch.
Pericom also offers the ability to fine tune the equalization set-
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.
