PCI VIO
Voltage
regulator
This module must have 5V and 3.3V supplied through the PMC connectors. Either
5V or 3.3V may be supplied for PCI I/O voltage and should be consistent with the
signalling standard of the PCI host bus. +12V and -12V are optional and may be
supplied to the PMC connectors as per PMC specifications.
Contained on the module are linear regulators for the FPGA VCCAUX and FPGA
RocketIO. A DC/DC converter supplies the core voltage for the FPGA and DSPs.
DC/DC converter
An International Rectifier IP1201 Power Block is used to supply the 1.5V core voltage
to the FPGA and 1.2V core voltage of the DSPs. The current limits are configured for
10A and 5A, respectively. The DC/DC converter is powered from the 5V supply.
Linear Voltage regulator
The FPGA VCCAUX and FPGA RocketIO voltages are supplied through linear
voltage regulators drawn from 3.3V.
