The 7700HD series Distribution Amplifiers provide reliable distribution of your 1.5GB/s HDTV and 270MB/s Standard Definition serial digital signals. The 7700DA6-HD-L features one auto-equalized input with passive loop thru which allows for cascading of multiple DA cards.

The 7700DA6-HD-L features an auto-equalized input with six reclocked outputs. The DA has been designed to reclock at 1.5GB/s and 270MB/s. In non-reclocking mode, it can be used as a SMPTE ST 310-1 or SMPTE ST 259-1/292-1 distribution product.

The 7700DA6-HD-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.


  • Reclocking mode for SMPTE ST 292-1 (1.5GB/s), SMPTE ST 259-1 (270MB/s)
  • DVB-ASI or HD/SD auto sensing
  • Non-reclocking mode for SMPTE ST 310-1 (also SMPTE ST 259-1, SMPTE ST 292-1)
  • 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

Ordering Information

NotesDue to the use of a passive loop through, the 7700DA6-HD-L is only recommended for applications with short input cable lengths. Care should be taken when designing a system using passive loop through modules. The length of loop through connections should be minimized and kept to cards within the same or adjacent frame. The specified cable length is further reduced with each successive loop through.
