See how this modular product fits in a frame:

The 7700DA6-L is an inexpensive 1x6 SD-SDI Distribution Amplifier with passive loop thru which allows for cascading of multiple DA cards. It amplifies serial digital video signal at rates of 19.4MB/s and 143MB/s to 540MB/s.

The 7700DA6-L features an auto-equalized input with six reclocked outputs. The 7700DA6-L 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 7700DA6-L 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
