Hello Zirui,

The 940N does not support this feature.

Hi Hamzeh,

If I use a SER who supports spread-spectrum function, does 940N will follow the SER and support SER's spread spectrum?

Hello Zirui,

If you pair the 940N with, for example, the 941AS or the 949 which is capable of tracking a triangular input spread spectrum clocking (SSC), then it should work.
