DS125DF410: About Reference Clock Specifications

Part Number: DS125DF410

Hi team,

I have a question about REFCLK_OUT duty cycle distortion.

In the datasheet, it is recommended 0.55 nsec or less, but it was about 1 nsec when I measured.

In this case, what kind of trouble can be considered?

Please let me know.

Best Regards,

    Greetings,

    We don't expect a problem when using 1nS duty cycle distortion. In data sheet, we specify just a typical value so this is not as crucial. What is more important is the level that should not be below 0.7V. Also, on time should be greater than 4nS.
