HATI (High Accuracy Timing IP)

Product Description

The HATI (High Accuracy Timing IP) is an FPGA core intended to provide sub-nanosecond synchronization accuracy by using 1/10 Gbps optical fiber links. The core is based on IEEE-1588, Sync-E and precise clock compensation to achieve subnano error levels. It doesn’t need any specific hardware and doesn’t interfere in the regular 1/10G traffic.

Key Features and Benefits

  • Dynamic compensation of asymmetries. Easily integrable.
  • Robustness & redundancy.
  • Distance range: over 80 km using fiber without amplifiers.
  • Sub-nanosecond time accuracy.
