Hello

I have a question about clocks. They are going to use a 12MHz crystal unit externally for HX2VL.
.In this case,  are there any rules regarding clock duty?
For example,  In HUBs of other manufacturers, there are many regulations of 40% to 60%.
 
Best Regards

Hello Arai-san,

The external clock duty should be within 45-55% with typical value of 50%.

Please refer to Table 3 in the App Note for more details.

Best Regards,
Sananya
