Overview

NetTimeLogic’s Time Of Day (ToD) Master Clock is a full hardware (FPGA) only implementation of a synchronization core able to synchronize a Time of Day sink via NMEA over UART. The whole message creation, algorithms and calculations are implemented in the core, no CPU is required. This allows running NMEA synchronization completely independent and standalone from the user application. The core can be configured either by signals or by an AXI4Light-Slave Register interface. This core only uses the second part of the clock, frequency and sub-second offset distribution shall be done in a combination with the PPS Master Clock.

All calculations and corrections are implemented completely in HW.

Key features

  • Time of Day Master Clock
  • Built-in UART transmitter with configurable baud rate
  • NMEA message creator
  • Support for NMEA GPZDA messages for time distribution
  • Hardware time conversion from seconds since midnight 1.1.1970 (Linux, TAI, PTP) into Time of Day format (hh:mm:ss dd:mm:yyyy)
  • Sending at the local second overflow
  • Local time can be set via registers
  • In combination with a PPS Master Clock from NetTimeLogic: synchronization accuracy: +/- 25ns
  • AXI4 Light register set or static configuration
