1:8 Dual-Link DVI Distribution Amplifier

Datapath - Datapath DL8


The Datapath dL8 is an eight output distribution amplifier for ultra-high resolution Dual-Link DVI signals.One Dual-Link DVI input, supporting graphics sources with pixel clocks up to 330MHz and resolutions beyond quad-HD (3840x2160), can be delivered to eight outputs on separate DVI-D (Dual Link) connectors.

The Datapath dL8 is the perfect companion to up to eight Datapath X4 stand alone display wall controllers, each of which can accept one of the Dual Link DVI outputs from the dL8 and select four arbitrary regions from it for display on standard DVI (Single Link)/HDMI monitors. In this way display walls of up to 32 screens can be assembled quickly and easily. And since the dL8 guarantees that all eight outputs are exactly locked to the source, all these 32 screens can be frame-locked for optimum display of creative, dynamic content.

The Datapath dL8 presents a fully programmable EDID to the graphics source, allowing simple control of resolution and frame-rate.

The EDID data can be programmed from a supplied Windows® application using the USB connection or can be simply sampled from a connected monitor or Datapath x4 using a front panel switch.

At high resolution, DVI signals cannot normally be guaranteed beyond 5m cables due to the nature of the signal losses inherent in the DVI cables and con- nectors. Datapath have added active equalization and re-clocking hardware on the dL8 input port which is able to compensate for these losses and

support cable lengths of up to 20m even at full dual-link resolutions (330MHz pixel clocks). Lower resolutions will allow even longer cable lengths. The high quality re-clocking signal processing ensures that any timing skews that might be introduced by lower cost input cables can be corrected within the dL8, maximising the signal quality of the output signals. 


Tech Specs

Support for up to 32-screen display walls when used in conjunction with up to 8 Datapath X4 stand alone display wall controllers.
Distribution and signal conditioning of arbitrary DVI source signals – any resolution or frame rate that can be sup- ported in either Single or Dual-Link DVI can be accepted.
