[83-121-201] 1x1, DVI-D Single Link Re-Clocker, Std Input


The 83-121-201 is a one input to one output DVI-D video distribution amplifier. This unit does equalization on the input signal to correct for long cables and re-clocks the output to remove jitter. All of the video connections are BNC connectors. This unit is intended to be used with DVI-D video up to a data rate of 3.4 Gbps.


  • DVI-D distribution amplifier (DA)

    Common Application

    The common application for this unit is to equalize and re-clock a DVI-D video signal after the signal passes through a long cable. This unit should be installed at the downstream end of the cable.

    Power Supply

    This unit has an isolated internal switcher power supply. The unit will operate correctly on 12-24 VAC or 10-34 VDC. The power input is protected so power can be applied in either polarity. The supply provides the internal electronics with power totally ground isolated form the power input. No opto electronics are used so the unit is not temperature limited by the isolated supply. The power connector is a four pin plug with jack screws so the power connection can support high vibration environments. In addition to the two pins used for power input, a third pin provides access to the internal electronics ground circuit. The fourth pin provides access to an internal chassis ground that connects to internal ESD protection devices.


    The package for this unit consists of a solid epoxy block. The internal electronics are assembled and tested before the encapsulation process. During the encapsulation the printed circuit board(s) are placed in a five sided box made of RTV mold parts. The cavity is filled with epoxy and the lid (top) of the mold is inserted. The curing process takes 24 hours. This type of package seals the electronics so water and contamination cannot affect the internal electronics. This type of package also provides superior resistance to shock and vibration compared to a metal or plastic box enclosure.
