The EL4544 is a high bandwidth 16-channel differential RGB

to 5-channel RGB single-ended RGB-HV video crosspoint

switch with embedded sync extraction. There are four

16-Channel input muxes, each capable of receiving a

complete RGB video signal, and five output muxes, each

capable of “seeing” any one of the four RGB inputs.

Additionally, the fifth input mux has an overlay “screen on

screen” function that can be displayed in conjunction with

any of the stacked RGB inputs.

The EL4544 has a fast disable feature to reduce power

consumption. The device also provides a presence of signal

indicator by looking for syncs on a designated channel.
