PI3HDX621FBEX

PI3HDX621 is the active-type 2:1 switch compliant to HDMI 1.4b specification, featuring equalized TMDS input and preemphasized TMDS outputs, with 3.4 Gbps high speed and long cable application. Two TMDS input ports switch fast in the built-in high speed Mux through port selection pins. Redriver boost the input signal quality, adjust known channel losses at the transmitter and restore signal integrity at the receiver. It offers doube termination or open drain output mode by output selection pin. TMDS output can shut down to reduce power dissipation by sink side HPD detection status. DDC 2:1 Mux and ARC drivers are integrated. PI3HDX621 is specified to operate over -40 to 85°C temperature range with 8kV ESD protection pins.
