NetTimeLogic’s PPS Master Clock is a full hardware (FPGA) only implementation of a synchronization core able to synchronize other nodes to a Pulse per Second output based on a reference time. The whole algorithms and calculations are implemented in the core, no CPU is required. This allows running PPS synchronization completely independent and standalone from the user application. The core can be configured either by signals or by an AXI4Light-Slave Register interface.
All calculations and corrections are implemented completely in HW.
