EL4544

Triple 16x5 Differential Crosspoint Switch

Capable of Operation in Single-Ended or

Differential Input Modes

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. 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.
