8936 Auto Reclocking DA
Introduction
The 8900 Series product line is a family of serial digital distribution ampli-
fiers (DA). It consists of a 2 RU frame which holds up to ten modules. A
variety of modules are available that can provide fanout, reclocking, mon-
itoring, or error detection and handling capabilities. Modules are selected
by the user to suit their particular requirements.
The 8936 Auto Reclocking DA module is a one input, eight output, auto
reclocking, auto cable equalizing DA. It operates with SMPTE 259M or EBU
Tech 3267 video formats.
The 8936 automatically selects the proper format from the incoming signal
and displays it via an LED at the front of the module. If no signal is present,
no LED will illuminate. If automatic selection is not desired, the user may
use a DIP switch to specify the desired signal format.
The module has auto-equalization for up to 300 meters of Belden 8281 (or
equivalent). There is an equalizer warning LED to indicate when the equal-
izer is approaching maximum capacity.

■ Loop-through input

■ Auto or manual format selection
■ Auto-equalization
■ Meets SMPTE 259M or EBU Tech 3267 standard
