Product Description

The PI3HDMI101 1:1 active ReDriver™ circuit is targeted for high-resolution video networks that are based on DVI/HDMITM 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. Diodes' 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, Diodes 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.

Diodes also offers the ability to fi ne tune the equalization settings in situations where cable length is known. For example, if 25meter cable length is required, Diodes' solution can be adjusted to 16dB EQ to accept 25meter cable length.
