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.
