Hi,

We got a question from the customer about LM3481-Q1.
Could you help us?

[Question]
They are considering using spread spectrum clock for external clock synchronization. Are there any concerns for this usage?

Hi Tateo,

Spread spectrum operation should be possible with the LM3481. Note that the resistor for on the FA/SYNC/SD pin should set the minimum frequency. What is the application minimum and maximum switching frequency?

Thanks,

Garrett
