Operation up to 3.4 Gbps per lane (340 MHz pixel clock) to 2 support 4K x 2K 24Hz (297 MHz) and 3D video format eTh I C configuration function with multiple system control (1080p, 1080i and 720p) signal integration of DDC channel MUX, Hot Plug Detection DEMUX, cable plug-unplug detection and HDMI 1.4 ARC TM Support up to 48-bit per pixel Deep Color transmitter help to save the extra requirement of GPIO control Integrated ARC(Audio Return Channel) and Rx Sense pins or control chip and provide optimized trace routing and function component reduction. Fast switching between two HDMI input ports Programmable termination settings at TMDS inputs help to Programmable equalizer, emphasis and amplitude settings to avoid the compatibility issue caused by non standard HDMI achieve optimized HDMI signal integrity source to determine the connection status of TMDS channel with proper termination voltage setting. The programmable Each input can be AC coupled or DC coupled, while the output termination setting supports double termination option output will maintain TMDS compliance DC coupled, between PI3HDMI521 and the HDMI receiver chip to ease the current steering signals reefl ction effect caused by improper impedance matching design Idle clock detection function for output squelch and auto and reducing jittery signals. standby PI3HDMI521 integrates ARC and supports video fast switching Integrated ESD protection on I/O pins to connector among HDMI ports. 8 KV contact per IEC61000-4-2, level 4 e dTh evice is fully compatible with HDMI 1.4 and supports 8 KV HBM backward compatibility to the DVI 1.0 standard.
