Thunderbolt™ Single Port Peripheral Reference Design


Design files


The TI Thunderbolt™ Single Port Peripheral reference design is optimized for Thunderbolt 2 systems which have a bandwidth of 20Gbps. The design utilizes the TPS65980 power management unit to reduce the BOM cost up to 50% and reduce the area about 40% over a discrete implementation. This design has been tested and certified at Intel for both self power and bus powered single port Thunderbolt systems.

  • Tested & Certified Thunderbolt Design for Bus & Self-Powered Peripherals
  • Provides a low cost and simple optimized design
  • TPS65980 PMU powers the needed supplies and provides system control signals
  • PCIe Connector for quick proto-typing w/ expansion cards
  • Design guide and high level schematics provided
Personal electronics

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
