The 7700 series Distribution Amplifier provides inexpensive distribution of your serial digital video signal at rates of 19.4MB/s and 143MB/s to 540MB/s. The 7700DA7 features an auto-equalized input with seven reclocked outputs.

It has been designed for use as a SMPTE 310M (19.4MB/s), DVB-ASI, M2s or SMPTE ST 259 distribution product. SMPTE 310M support is selected by setting a rate select jumper.

The 7700DA7 occupies one card slot and can be housed in the 1RU 7801FR frame which holds up to four single or two dual slot modules, the 3RU 7800FR frame which has a 15 slot capacity, the portable 3RU 350FR frame which has a 7 slot capacity, or a standalone enclosure which holds a single module.


  • Supports up to 540MB/s operation
  • DVB-ASI compatible
  • Non-reclocking mode for SMPTE 310M
  • Features independent isolated output drivers to ensure no cross channel loading effects (i.e. no need to terminate unused outputs)
  • VistaLINK® capable for remote monitoring, control and configuration capabilities via SNMP; using VistaLINK® PRO, CP-2116E or CP-2232E Control Panels. VistaLINK® is available when modules are used with the 3RU 7800FR frame and a 7800FC VistaLINK® Frame Controller module in slot 1 of the frame
