Description
Pericom Semiconductor’s PI3HDMI341AR 3:1 active switch circuit is targeted for high-resolution video networks that are based on DVI/HDMI standards and TMDS signal processing. The PI3HDMI341AR 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 1.65 Gbps provides 8- 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 PI3HDMI341AR is the industry’s fi rst 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 PI3HDMI341AR 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: 2meter, 10meter, 15meter, and 20 meter. Pericom also offers the ability to fi ne tune the equalization settings in situations where cable length is known. For example, if 25meter length cable isrequired, Pericom's solution can be adjusted to 16dB EQ to accept 25meter cable length. 06-0340

Application Information
All VCC pins are recommended to have a 0.01uF capacitor tied from VCC to GND to fi lter supply noise TMDS inputs Standard TMDS terminations have already been integrated into Pericom’s PI3HDMI341AR device. Therefore, external termina- tions are not required. Any unused port must be left fl oating and not tied to GND. HPD Pins The HPD pins on the PI3HDMI341AR require external pull down transistors to maintain a 0V signal when port is not selected, as follows: This architecture allows EDID readability when the DTV is power off or power on. SCL and SDA pins For EDID readability when the Sink is power off, 3 EEPROMs will be needed as follows PI3HDMI341AR HPD1 HPD2 HPD3 100K 100K 100K HPD HPD HPD PI3HDMI341AR SCL1 SDA1 SCL2 SDA2 SCL3 SDA3 HDMI RX 06-0340
