The ADV3002BSTZ is a HDMI?/DVI Link Switch features equalized transition minimized differential signalling (TMDS) inputs, ideal for systems with long cable runs. It includes bidirectional buffering for the DDC bus and CEC line, with integrated pull-up resistors for the CEC line. Additionally, the switch includes an EDID replication function that enables one EDID EEPROM to be shared for all four HDMI ports. The primary function of the ADV3002 is to switch up to four HDMI/DVI sources to one HDMI/DVI sink. Each HDMI/DVI link consists of four differential, high speed channels and four auxiliary single-ended, low speed signals. The high speed channels include a data-word clock and three TMDS data channels running at 10x the data-word clock frequency for data rates up to 2.25Gbps. The four low speed control signals are the display data channel (DDC) bus (SDA and SCL), the consumer electronics control (CEC) line and the hot plug detect (HPD) signal.
