The PI3HDMI341ART 3:1 active switch circuit is targeted for high-resolution video networks that are based on DVI/HDMI standards and TMDS signal processing. The PI3HDMI341ART is an active 3 TMDS to 1 TMDS receiver switch with Hi-Z outputs. The device receives differential signals from selected video components and drives the video display unit. It provides three controllable output swings that can be controlled through a single bit. The allowable output swings are 500mV, 750mV and 1000mV. 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 switch together with the high speed switch 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 12-bit deep color support, which is offered by HDMI revision 1.3. Due to its active uni-directional feature, this switch is designed for usage only for the video receiver’s side. For consumer video networks, the device sits at the receiver’s side to switch between multiple video components, such as PC, DVD, STB, D-VHS, etc. The PI3HDMI341ART is the industry’s irst active DVI/HDMI switch compatible with HDMI 1.1, 1.2, and 1.3 which ensures transmitting high-bandwidth video streams from video components to the display unit. The PI3HDMI341ART also provides enhanced robust ESD/EOS protection of 8kV, which is required by many consumer video networks today.
