The ADV3002 is a complete HDMI™/DVI link switch featuring equalized transition minimized differential signaling (TMDS) inputs, ideal for systems with long cable runs. The ADV3002 includes bidirectional buffering for the DDC bus and CEC line, with integrated pull-up resistors for the CEC line. Additionally, the ADV3002 includes an EDID replication function that enables one EDID EEPROM to be shared for all four HDMI ports. The ADV3002 is provided in a space-saving, 80-lead LQFP surface-mount Pb-free plastic package and is specified to operate over the 0°C to 85°C temperature range.
