We can find the calculate way when RT>5k,but I can't find the calculate way when RT≤5k

Could you help to tell us how to calculate the frequency when RT≤5K。

Hi user5195014,

You can find oscillator frequency vs Rt-Ct curves on page 7 figure 10 in the datasheet. Could you help me understand why Rt > 5kOhm is prohibitive for your design?

Best Regards,
