Synchronized Crystal Oscillator (SXO) Application Note

2009-10-14T09:18:00.000-07:00

• 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)

2009-09-11T14:05:00.000-07:00

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.
