Question, PN5180 CLOCK_CONFIG

Dear team,

 

I would like to ask about CLOCK_CONFIG setting of PN5180.

Now my customer is using PN5180 for prototyping, and they have a question about its CLOCK_CONFIG setting.

They are using 27.12MHz crystal and they understand that the CLOCK_CONFIG setting of PN5180 should be 08h for 27.12MHz crystal use according to its datasheet.

After some tries, they saw that when CLOCK_CONFIG is set to 3h then RF output does work correctly but when they set CLOCK_CONFIG into 008h then RF output does not work. And they found the setting of CLOCK_CONFIG is also 03h for your EVA board.

They believe that the description of CLOCK_CONFIG in datasheet is incorrect.

Is it true?

If any other technical documents which describing the setting of CLOCK_CONFIG, please let me know.

 

Best Regards,

Miyamoto
