8 Power consumption
The CPC505 module is designed with due consideration of optimal power consumption and
distribution. However, it is necessary to observe certain requirements which are essential for
stability and reliability. The table below shows the maximum permissible supply line voltages,
exceeding which could result in damages to the module. The power supplies with which the
CPC505 will be used must be tested for compliance with these requirements.
The table provided defines the operating ranges of the various power supply voltages of the
module. If the supply voltages are outside of these ranges, the functionality of the module cannot
be guaranteed.
The backplane must provide optimum distribution of +3.3 V and +5 V supply voltages. Only
backplanes with two voltage planes for each of the voltages are recommended.
The connections between the power supply lines and the backplane should provide minimum
losses and guarantee stable performance. Long supply lines, conductors with small cross sections,
and connections with high resistance should be avoided.
The modules should be supplied from an external DC power supply with the characteristics given
in section 2.1:
