HL8548-G : RTC accuracy

Does anyone knows where I can find information about internal HL8 RTC accuracy?
I did’nt find anything in Technical specification.

Thank you.
Best regards,

Hello Vianney,
Thank you for you support again.

I’m looking for RTC accuracy in part per million (ppm) to know how much time RTC clock will take being late/early after few years running without any new synchronising from outside.

I’ve already search in technical spec but nothing about RTC spec (just RTC battery… ).

I had a look to MSORTCSTATUS too. But it seems not to show any RTC specification. Just status.


It seems that my Airprime RTC is currently shifting for about few seconds a day.
No one has some of a piece of answer to Airprime internal RTC accuracy here?
