MAX3845UCQ+TD

MAX3845UCQ+TD is a TMDS® 2-to-4 fanout switch and cable driver for multimonitor distribution of DVI™ or HDMI™ signalling up to 1.65Gbps. Both inputs and outputs are standard TMDS signalling 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. It includes selectable output preemphasis that extends output cable reach up to an additional 7m. It is used in applications such as digital signage and industrial display, PC monitor distribution, home A/V receivers, DVI/HDMI distribution amplifiers, and DVI/HDMI crosspoint switches.

• Save power by turning off unused outputs
• Each output independently selects input 1 or input 2

• Residual random jitter is 1.5psRMS typical at (TA = +25°C)
• Input resistance is 50 ohm typical at (VCC = 3.0V to +3.6V)
• Input return loss is 19dB typical at (VCC = 3.0V to +3.6V, TA = -10°C to +85°C)
• Rise/fall time is 90ps typical at (20% to 80% (TA = 0°C to +85°C))
• Operating temperature range from -10°C to +85°C
• 100-pin TQFP-EP package
