... 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. ...

... BLUE CHANNEL V Functional Overview Overall Functionality The EL4544 is a video crosspoint switch that has 16 (RGB differential) input channels (with H and V sync embedded in their common-modes) which connect via an internal crosspoint mux to 5 (RGB + HV) single-ended output channels. The 5th output group has enhanced features that include: a pixel-by-pixel overlay mux and auto-calibrated offset cancellation ...

... When Toggle mode is active and the overlay switch is disabled, the EL4544 will automatically toggle between "thru" and overlay selections for alternate pulsing of the calibrate signal. Thus, every alternate calibrate pulse will override the selected " ...
