Description

The PMP9407 reference design provides all the power supply rails necessary to power the multi-gigabit transcievers (MGT) in Xilinx's Virtex® Ultrascale™ FPGAs.  This design uses a 5V input and has a PMBus interface for current and voltage monitoring, margining, timing delays, and fault monitoring.  It uses two TPS544B20's which feature internal current sensing and eliminate the need for an external current sense resistor.  This design also meets Xilinx's low output voltage ripple requirements of the MGT rails.

Features
  • 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
  • MGTAVCC and MGTAVTT have lossless MOSFET current sensing, eliminates need for sense resistor
