2 How to get started
2.1 Power requirements
The absolute maximum power consumption for this module is 9.0 W. This does however
include the 0.5 W for the optional PIN or APD optical input modules, and 0.8 W for the AES
I/O option, and also varies considerably with the combination of input and output video
standards used. If the module will always be used with the same combination of input and
output standards, the table below can be used to determine the actual maximum power
consumption, and to determine how many modules can safely be used in one frame.
Note that the module will draw all its power from +5 V. Check the +5 V rating of
the power supply, generally it will be lower than the rating for the entire supply.

Table 2: Maximum power consumption as a function of video standards used
Note that the figures in the table above include 0.5 W for the optional PIN or APD
module, and 0.8 W for the AES I/O option. These numbers can be deducted if the
corresponding option has not been purchased for the module(s) in question.
Even if the AES I/O option has been purchased, ~0.3 W can be deducted from
the table values if all four AES I/Os are used as inputs.
