Synchronized Crystal Oscillator (SXO) Application Note

• Jitter- Demo shows that multiple SXO's in sync together has better jitter performance than one individual SXO. This can be accomplished by starting with a jitter measurement with just one SXO running, then turning on two or more other SXOs making sure that at least one odd and one even SXO is on.

• Synchronization- Demo shows SXO's in an ensemble working in sync both frequency
and phase wise. Using one SXO as a reference for the others, the frequency and phase can be compared between SXO units that are powered up.

• Scalability- Allows for experimentation of adding or dropping off SXO's without
losing synchronization. The switches provided can be used to add or eliminate units from the overall operating group.

Redundancy- Demo allows for simulating clock failure via dropping off multiple SXO's.The switches provided can be used to add or eliminate units from the overall operating group.

• Hot Swap- Robustness experiments can be performed. Units can be physically
removed from their sockets and replaced to simulate the hot swap feature operation.

Low Jitter Performance Synchronous Crystal Oscillator (SXO)

Using NEL Frequency Controls' new synchronous clocking architecture, every oscillator in the system is synchronized within a common feedback loop. Phase and frequency are locked, offering the advantages of both synchronous and asynchronous architectures.
