IRIG Master

NetTimeLogic’s IRIG Master Clock is a full hardware (FPGA) only implementation of a synchronization core able to synchronize other nodes via IRIG-B007/IRIG-G006. The whole encoding, conversion, algorithms and calculations are implemented in the core, no CPU is required. This allows running IRIG 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.

IRIG Master


  • IRIG-B Master Clock
  • Supports IRIG-B007 and IRIG-G006 format (compatible with B004, B005, B006 and B007 IRIG-B Slaves)
  • Optional supports all IRIG-B000 - B007 codes, changeable at runtime
  • Optional supports Control Bits for IRIG-B000/B001/B004/B005
  • PWM, DCLS encoding
  • Optional AC encoding and amplitude modulation for IRIG-B120 - B127 and IRIG-G146(requires an external DAC)
  • Output delay compensation
  • Additional seconds correction to convert between TAI and UTC time (or any other time base)
  • AXI4 Light register set or static configuration
  • IRIG resolution with 50 MHz system clock: 20ns (DCLS)
