Description

Napatech SmartNICs can be configured to output a PPS pulse representing the phase (second tick) of the time stamp clock. The PPS output enables synchronization of third-party equipment to the SmartNIC time stamp clock. PPS provides reference for phase and frequency synchronization of the connected third-party equipment.

Illustration

This figure shows a system configuration where an NT SmartNIC outputs a PPS signal on the external time synchronization connector enabling synchronization of third-party equipment to the SmartNIC time stamp clock.
Note: On NT200A02 and NT200A01 SmartNICs the RJ45 and SMA ports on the external time synchronization connector are replaced by separate RJ45 and SMA time synchronization connectors.
