Description
Pericom Semiconductor’s PI3HDMI101 1:1 active ReDriver™
circuit is targeted for high-resolution video networks that are
based on DVI/HDMI^TM standards and TMDS signal processing.
The PI3HDMI101 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/DVI channel also has slower speed, side
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 Bandwidth of 2.5 Gbps provides 36-
bit Deep Color™ support, which is offered by HDMI revision
1.3. The PI3HDMI101 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:
1meter to 20meters and color depths of 8bit/ch, or 12bit/ch.
Pericom also offers the ability to fine 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.
