Description

The TIDA-00389 design is an optimized power solution for Xilinx® Zynq® 7010 FPGA/SoC (out of the Zynq® 7000 series family of products). It targets ADAS applications where customers opt to use FPGA instead of Multicore DSP or MPU.  This design runs from a single intermediate 3.3V or 5V power supply rail and provides a complete solution to power the Xilinx® Zynq® 7010. DDR memory termination and a 5V supply for a CAN Transceiver are also implemented. A LM3880 provides power up and power down sequencing.  The design is tested and optimized for automotive applications.

Features

  • Provides all the power supply rails for a Xilinx® Zynq® 7010 based  ADAS system
  • Individual High efficiency switching regulators for low power consumption and heat generation
  • All switching regulators operate at >2MHz for optimized size and cost of external components and to reduce noise in the AM radio band
  • Voltage sequencing for all supply rails implemented on board
  • Dedicated DDRx memory termination available
  • This circuit is tested and includes design considerations
