The White Rabbit PTP Core can operate in one of the following modes:

|
|
• GrandMaster: WR Master synchronized to an external 1-PPS and 10 MHz
|
|
|
clock signal, propagates precise timing to other WR-compliant devices
|
|
|
• Master: WR Master with free-running oscillator, propagates precise

|
timing to other WR-compliant devices
|
|
|
• Slave: synchronizes its internal oscillator to another WR Master
