Operating Conditions

Safety

This module presents no hazard to the user.

EMC

This module is designed to operate from within an enclosed host system,
which is built to provide EMC shielding. Operation within the EU EMC
guidelines is not guaranteed unless it is installed within an adequate host
system.
This module is protected from damage by fast voltage transients originating
from outside the host system which may be introduced through the output
cables.
Short circuiting any output to ground does not cause the host PC system to
lock up or reboot.

Power Requirements

This module must be fixed to a TIM40 compliant carrier board. Additionally, a
3v3 power source must be provided to the fixings. This is normally achieved
by means of a power source provided directly through conducting pillars on
the carrier board.
The SMT332/372 TIM is in a range of modules which must be supplied with a
3.3v power source. In addition to the 5v supply specified in the TIM
specification, these new generation modules require the additional 3.3v supply
to be presented onto the two diagonally opposite TIM mounting holes.
Although no damage should result from not supplying 3.3v (the module
obviously will be inoperable), prolonged operation in these circumstances is
not recommended.
This module is then not directly compatible with earlier generations of TIM
motherboards, although the 3.3v supply can be connected from a separate
source. The module is however, compatible with the latest generation of
Sundance TIM carrier boards such as the SMT320 (PCI), SMT327 (cPCI) and
SMT328 (VME).
External ambient temperature must not exceed the limits of 0 to 40°C, and
relative humidity not greater than 95% (non-condensing).

Power Consumption

The power consumption of this TIM is dependant on the operating conditions
in terms of core activity and i/o activity. The maximum power consumption is
6W.
