Section 3 — Functional Description
Output Modules
There are three types of output modules available: Serial Digital Output,
Analog Output, and Timed Aux Output.
Serial (Digital) Output Modules (064821)
The Serial Output Modules convert the output signals from balanced
(differential) to unbalanced (coax) mode
Analog Output Module (064819)
The Analog Output Module is used to output the M/E 2 program and
switched preview to monitors.
Timed Aux Output Module (064852) (Slot C16 and 17)
The basic function of the Timed Aux Output Module is:
■ Generate aux buses 3A through 5B
There are eight identical channels on the module but only six are used. In
one typical channel, the aux bus signal arrives from the Crosspoint
Module. The signal is de-serialized, descrambled, and presented to a
RP-125 decoder ASIC.
The ASIC is used in a standard fashion to re-synchronize and demultiplex
the signal. The timing signal is also used to provide delay information to a
pair of HSP–9501 delay lines. The delayed Y and C components of the
signal are multiplexed together by RP–125 encoder. Finally, the signal is
scrambled and serialized.
The Timed Aux Mezzanine is mounted on the double-wide Timed Aux
Output module.
For the Timed Aux Output Module to function, either the Frame Store or
the Timed Aux Control Module must be installed in cell A17. These
modules have circuitry that latches the VID Data and control data, and
sends it on the backplane to the Timed Aux Output module.
NOTE:
The Timed Aux Output module will not work with the Extender Module.
