The PMP9408 reference design provides all the power supply rails necessary to power the multi-gigabit transcievers (MGT) in Xilinx's Virtex® Ultrascale™ FPGAs.  It utilizes a PMBus interface for current and voltage monitoring and meets Xilinx's low output voltage ripple requirement.  This design uses a 5V input and offers a low cost discrete solution.

  • Provides all the power rails needed to power MGT rails in a Xilinx  Virtex® Ultrascale™ FPGA
  • Design optimized to support a 5V input
  • Low output voltage ripple < 10mV
  • On board power up and power down sequencing
  • PMBUS interface with output voltage and current reporting
  • Discrete low cost solution
