Maxim's new MAX3845/MAX4814E is a 2:4 fanout switch chipset for HDMI and DVI applications. In this two-chip solution, the MAX3845 provides switching, fanout, and cable driving for TMDS signals, while the MAX4814E provides I²C control of the MAX3845 and handles all switching of the DDC, 5 V, and HPD signals. These devices can easily be combined to create complete 2:4, 4:4, and 2:8 DVI switches with full I²C control. The chipset is ideal for flexible, multidisplay digital signage and PC monitor applications. In addition to performing all TMDS switching, the MAX3845 provides input equalisation and output pre-emphasis. In contrast to typical HDMI/DVI systems that experience signal-reflection problems between interface ICs and connectors, the MAX3845 offers a selectable, higher-output current that enables the use of 200 Ω back-termination resistors to absorb output reflections. To complete this two-chip solution, the MAX4814E provides ±15 kV of ESD protection on all of its I/O ports, and offers either I²C or parallel programming of the MAX3845.
