TLK10031: RefClk Query

Hi Kevin,

Can you clarify the difference between free run clock versus locked reference clock? Sorry, I'm unfamiliar with this vocabulary.

Best,

Lucas

Hi Lucas,

Please find the explanation below

1. Free Run:

• Free run refers to a clock that operates independently without being synchronized or controlled by another external signal or reference.

• A free-running clock generates frequency at its own rate, unaffected by any other clock. It's not locked to any external reference.

2. Locked Clock:

• A locked clock refers to a clock that is synchronized or "locked" to a reference signal or external clock source.

• When a clock is locked, it means its frequency and timing are in phase with the external reference, often using phase-locked loops (PLLs) or other synchronization mechanisms.

Thanks

Kevin

Hi Lucas,

Thanks for your inputs.

Can we use Locked reference clock also, if it meets the above requirements.

Thanks

Kevin
