Description
Pericom Semiconductor's PI3HDMI431AR 3:1 active switch circuit is targeted for high-resolution video networks that are based on DVI/HDMITM standards and TMDS signal processing. The PI3HDMI431AR 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 HDMITM/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/HDMITM Bandwidth of 2.5 Gbps provides 12bit deep color support, which is offered by HDMITM 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 PI3HDMI431AR is the industry's first active DVI/HDMITM switch compatible with HDMITM 1.1, 1.2, and 1.3 which ensures transmitting high-bandwidth video streams from video components to the display unit. The PI3HDMI431AR also provides enhanced robust ESD/EOS protection of 12kV, which is required by many consumer video networks today. The Optimized Equalization provides the user a single optimal setting that can provide HDMITM compliance for all cable lengths: 1meter to 20meters and color depths of 8bit/ch, or 12bit/ch. Pericom also offers the abiility 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.

Supply Voltage All VDD pins are recommended to have a 0.01uF capacitor tied from VDD to GND to filter supply noise TMDS inputs Standard TMDS terminations have already been integrated into Pericom's PI3HDMI431AR device. Therefore, external terminations are not required. Any unused port must be left floating and not tied to GND.
