Output Power Signals
The table below contains the output power signals for the NTx-Pro IP Engine.
NTx-Pro Power Output Signals
Name Volts (V) Current (A) Notes
VIN
5 - 16V
a 0.4A FILTER_VIN can be used as an output
from the NTx-Pro, if PWR is used to power
the NTx-Pro. Refer to the section,
“Input
Power Signals” on page 39 .
Current per pin is 0.4A. Maximum current
sink by user circuitry through all VIN pins
must not exceed 0.8A.
3.3V 3.3V 0.4A 3.3V is generated by a switcher connected
to FILTER_VIN.
3.3V is available for user circuitry, through
the J4 and J5 connectors.
Current per pin is 0.4A. Maximum current
sink by user circuitry through all VIN pins
must not exceed 1.0A.
2.5V 2.5V 0.4A 2.5V is generated by a switcher connected
to FILTER_VIN.
2.5V is available for user circuitry through
the J4 connector.
Current per pin is 0.4A. Maximum current
sink by user circuitry through all VIN pins
must not exceed 0.9A.
GND Ground - - - 0 volts relative to other voltages on the
NTx-Pro.
VIN 5 - 16V
5V is recommended
a
.
Filtered DC power supplied from two input power
pins (5, 6) on the J4 I/O connector.
NOTE! VIN is filtered power to the NTx-Pro board. If
you implement this option, do not power the board
through the J3 Molex connector. Leave PWR and
RET unconnected in this case.
NOTE! Refer to the section, “Output Power Signals”
on page 40 for the values of current supplied through
these pins.
GND Ground 0 volts relative to other voltages on the NTx-Pro.
a. 5V is the recommended input to the NTx-Pro IP Engine to reduce power consumption. Refer to the tables under
“Power Consumption” on page 41 .
