LM25149-Q1: crystal module integrated inside the chip

Mingkang Song

Part Number: LM25149-Q1

For a typical DCDC chip, does the clock generation have a crystal module integrated inside the chip?

From an application point of view, do you need to consider or test the gain margin parameters of the internal crystal of the chip itself? Thanks

Hello Mingkang,

This device does not have an integrated crystal module.

Hope this helps,

David.

Hi David. I found this in the datasheet. Is it not an integrated crystal module in the red box?

Hello Mingkang,

No, the PLL generates a clock signal using electronic components, a crystal uses quartz and its piezoelectric effects to oscillate and generate a clock signal. l hope this helps.

David.
