Description
Pericom Semiconductor’s PI3HDMI101-A 1:1 active redriver
circuit is targeted for high-resolution video networks that are
based on DVI/HDMI
The PI3HDMI101-A is an active redriver with Hi-Z outputs.
The device receives differential signals from selected video
components 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
band signals, that are required to be switched. Pericom’s solution
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 channels,
Pericom can successfully eliminate deterministic jitter caused by
long cables from the source to the sink. The elimination of the
deterministic jitter allows the user to use much longer cables (up
to 25 meters).
The maximum DVI/HDMI
bit deep color
1.3. The PI3HDMI101-A 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
1meter to 20meters and color depths of 8bit/ch, or 12bit/ch.
Pericom also offers the abiility to fi ne tune the equalization
settings in situations where cable length is known. For example,
if 25meter cable length is required, Pericom's solution can be
adjusted to 16dB EQ to accept 25meter cable length.
