AM2634: deviation of Internal Oscillator

Fan_Zhang

Part Number: AM2634

Tool/software:

Hi, experts,

There are Internal Oscillator in AM2634, RCOSC32K and CIO's RCCLK_10M, but the accuracies of them are not mentioned in datasheet. Can you please help to share?

Thanks.

Hi Fan,

Apologies for the late reply.

The RCOSC clock of 10MHz has the below specifications

Parameter	Min	Nominal	Max	Units
Freq(trimmed)	8	10	12	MHz
Duty Cycle	40		60	%
Temperature	-40	30	150	°C

I have reached out to our experts on getting details of RCOSC clock of 32kHz, will let you know once I find the same.

Thanks,

Tejas Kulakarni

May I understand the accuracy of 10MHz RCOSC is -20% ~ +20%?

Hi, Tejas,

Is this accuracy for all temperatures?
