ADVANCE INFORMATION - COMPANY CONFIDENTIAL PI3HDMI301 3:1 Active Switch for HDMI Signals with Optimized Equalization for Enhanced Signal Integrity Features Description Pericom Semiconductors PI3HDMI301 3:1 active switch circuit Supply voltage, V = 3.3V 5% DD is targeted for high-resolution video networks that are based Each of the three input ports can support HDMI or DVI on DVI/HDMI standards and TMDS signal processing. The signals PI3HDMI301 is an active 3 TMDS to 1 TMDS receiver switch Supports both AC-coupled and DC-coupled inputs with Hi-Z outputs. The device receives differential signals from Supports DeepColor selected video components and drives the video display unit. It High Performance, up to 2.5 Gbps per channel provides controllable output swings, as well as provides a unique advanced pre-emphasis technique to increase rise and fall times Switching support for 3 side band signals which are reduced during transmission across long distances. (SCL, SDA and HPD) 5V Tolerance on all side band signals Each complete HDMI/DVI channel also has slower speed, side band signals, that are required to be switched. Pericoms solution SCL, SDA, and HPD pins are the only pins that can support provides a complete solution by integrating the side band switch HOT INSERTION together with the high speed switch in a single solution. Using Integrated 50-ohm (10%) termination resistors at each high Equalization at the input of each of the high speed channels, speed signal input Pericom can successfully eliminate deterministic jitter caused by TMDS input termination control on all high speed inputs long cables from the source to the sink. The elimination of the HDCP reset circuitry for quick communication when deterministic jitter allows the user to use much longer cables (up switching from one port to another to 25 meters). Con gurable output swing control The maximum DVI/HDMI Bandwidth of 2.5 Gbps provides 36-bit Con gurable Pre-Emphasis levels Deep Color support, which is offered by HDMI revision 1.3. Con gurable De-Emphasis Due to its active uni-directional feature, this switch is designed for usage only for the video receivers side. For consumer video Optimized Equalization networks, the device sits at the receivers side to switch between Single default setting will support all cable lengths multiple video components, such as PC, DVD, STB, D-VHS, 8kV Contact ESD protection on all input data/clock channels etc. The PI3HDMI301 also provides enhanced robust ESD/EOS per IEC61000-4-2 protection of 8kV, which is required by many consumer video Propagation delay 2ns networks today. High Impedance Outputs when disabled The Optimized Equalization provides the user a single optimal Packaging (Pb-free & Green): setting that can provide passing results for HDMI jitter tests for 80-pin LQFP (FF80) all cable lengths: 1meter to 20meters with DeepColor support up to 36bits. 64-pin TQFN (ZL64) Pericom also offers the ability to ne 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.
