Illustration
The NT20E3-2-PTP SmartNIC has 3 time synchronization connectors, which can be configured separately for input or output (see Configuring the Time Synchronization Connectors and the Time Synchronization Time and Frequency Reference Priorities). This figure shows an NT20E3-2-PTP SmartNIC and the location of its time synchronization connectors.
The external time synchronization connector contains a robust SMA connector, which ensures a more secure interface connection.
