NetTimeLogic’s Time Of Day (TOD) Slave Clock is a full hardware (FPGA) only implementation of a synchronization core able to synchronize to a Time of Day source via NMEA, UBX, TSIP or ESIPover UART. The whole interface handling, message parsing, algorithms and calculations are implemented in the core, no CPU is required. This allows running TOD synchronization completely independent and standalone from the user application.
