ASI – SMPTE Distribution Amplifiers

Part Number:



The Evertz 7700 series Distribution Amplifiers provide inexpensive distribution of your serial digital video signal at rates of 19.4Mb/s and 143Mb/s to 540Mb/s. The 7700DA features an auto-equalized input with four reclocked outputs. The 7700DA-N offers an auto-equalized input with four non-reclocked outputs.

They both have been designed for use as a SMPTE 310M (19.4Mb/s), DVB-ASI, M2S or SMPTE 259M distribution product. SMPTE 310M support is selected by setting a rate select jumper (for 7700DA only).
