EL4544

Triple 16x5 Differential Crosspoint Switch with Single-Ended or Differential Input Mode Operation

OVERVIEW

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.
