Power Supplies
Due to the close packing of components between PMC Side 1 and the host module,
power consumption is limited to 4.0W for 10.0mm standoffs (this increases to 6.0W
for 13.0mm standoffs). The total consumption for Side 1 and Side 2 of the module
shall not exceed 7.5W, and represents the total power drawn from all power rails
provided at the connector (+5V, +3.3v, +VI/O, +12V,-12V, +3.3Vaux).
For this reason it is recommended that you analyse the total FPGA device power
drawn by using Xilinx XPOWER before implementing your design in the FPGA.
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
signaling 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. 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.
