2.16. Precision Time Protocol Interface

The Precision Time Protocol (PTP) interface is available when you enable Enable IEEE 1588 PTP option in the PTP tab. When selected, the IP generates PTP based 1-step or 2-step TX and RX timestamps. The IP requires the IEEE 1588 96-bit time-of-day (TOD) input.
The table below depicts the interface details for different number of ports. Each port within a reconfiguration group supports a separate TOD clock.
