4.2.1.2 Power Requirements
Make sure that the board is used in an AdvancedTCA shelf connected to -48 VDC up to -60 VDC
(rated voltage), according to Telecommunication Network Voltage (TNV-2).
A TNV-2 circuit is a circuit whose normal operating voltages exceed the limits for a safety-extra-
low-voltage (SELV) under normal operating conditions, and which is not subject to
overvoltages from telecommunication networks.
On board voltages are 3.3 VDC, 2.5 VDC, 1.8 VDC and 1.0 VDC:
 3.3 V voltage is generated from the -48 V AdvancedTCA power by a DC/DC converter with
galvanic isolation suitable for TNV-2 circuits.
 2.5 V, 1.8 V and 1.0 V voltages are derived from the 3.3 V power.
