MODULE OVERVIEW
The 4110 DVB-ASI DA provides distribution of a DVB-ASI, DVB-SSI or SMPTE 310M
input signal to eight outputs. The module handles data rates from 19.39 Mb/s to 270 Mb/s.
Signal presence detection and cable equalization is provided on the module.
As shown in the block diagram below, the input signal passes through a receiver/equalizer
circuit. The signal strength of the equalized output is monitored by the module processor
for cable equalization and EQ warning information available to the user via the optional
Avenue control interfaces. The DVB-ASI outputs are buffered then AC coupled to the
BNCs on the rear of the frame providing eight serial outputs for distribution.
Power is derived from the ± 12 volt frame power. It is regulated to the required +5 volts
for the module by on-board regulator. The module is fused with a resettable fuse device. If
the fuse opens due to an overcurrent condition, the module will lose power. After pulling
the module, the fuse will reset automatically requiring no replacement fuse.
Module ID information (slot location, software version and board revision) can be
monitored by the optional frame System Control module and read using the optional
interfaces available.
