LMK00105: LMK00105SQ clock source solution

Part Number: LMK00105
Other Parts Discussed in Thread: LMK00304

I have used the LMK00105SQ in my small board, right now, we want to design the test board to test my small board in the manufactory.

Could you please suggest how to provide the clock source to LMK00105SQ in my test board?

The snapshot is the LMK00105SQ circuit in the small board.

Your snapshot did not come through (broken link?). Can you please retry sending the image?

What is your clock source's frequency and driver signaling format?

Regards,
Alan

I need a 24M Hz diff pair clock into the LMK00105, could you please provide sample solution to produce the clock?

Hi Jason,

If you are looking for a differential clock source for use in the test board, you can use a 24MHz crystal (or crystal oscillator, XO) together with LMK00304. This device has four outputs, maybe you can test 4 small boards together at a time.
