MAXIM MAX3845UCQ+D

The MAX3845 is a TMDS 2-to-4 fanout switch and cable driver for multimonitor distribution of DVI or HDMI signaling up to 1.65Gbps. Both inputs and outputs are standard TMDS signaling as per DVI and HDMI standards. Because TMDS links are “point-to-point,” buffering is required for fanout applications. Four DVI/HDMI TMDS outputs are provided for fanout distribution. Each TMDS output can be independently sourced from either input or can be turned off. Each TMDS input or output is composed of four differential channels that can be arbitrarily assigned to the three data signals and the 1/10th-rate clock. The data rate depends on resolution, but it can vary from 250Mbps (VGA) to 1.65Gbps (UXGA or 1080p/60). The MAX3845 2:4 DVI/HDMI fanout switch and cable driver accept differential CML input data at rates of 250Mbps up to 1.65Gbps (individual channel data rate).
