description

The HATI (High Accuracy Timing IP) is a FPGA core intended to enable sub-nanosecond synchronization accuracy once it is integrated onto a third-party hardware that it is connected to Safran’s WR-Z device by using optical fiber links. The IP core is able to achieve this performance thanks to the use of White Rabbit protocol (based on IEEE-1588, Sync-E and precise clock compensation).
