4.1.7.4. External Time-of-Day Module for 1588 PTP Variations
25G Ethernet Intel FPGA IP cores that include the 1588 PTP module require an external time-of-day (TOD) module to provide the current time-of-day in each clock cycle, based on the incoming clock. The TOD module must update the time-of-day output value on every clock cycle, and must provide the TOD value in the V2 format (96 bits) or the 64-bit TOD format, or both.
