Long Term RC Osc stability and Ageing Info

Hi All,

What is the long term (15-20 years) stability and ageing data for the RC OSC, not being crystal based? how would it impact counter delays timing?

 

Thanks,

Hi Amine,

Hi Amine,

yes, we have some ageing test results

HTOL drift of 25K OSC appears at first of three read points after HTOL stress (168 hours). (HTOL Stress = 3 lots * 80 devices tested at 125C). At HTOL 168h drift increase is maximum while at following read points increase is not significant.

ELFR Drift: Also we’ve seen some OSC 25k drift at ELFR test (24hr at T=125C): ~300 Hz drift

Maximum value of the HTOL drift after 1000hr is 1.2 kHz

Thanks a lot for your interest in our products!

Regards,

Pavlo

P.S. 1000hr at 125C is

P.S. 1000hr at 125C is equivalent of 8608hr at 87C
