HXFO pin capacitance (Cpin)

[MURAKAMI KAZUHIRO]

nRF54LM20A: 

C_pin is the pin input capacitance on pins XC1 and XC2.

Could you provide the typical, maximum, and minimum values of Cpin?

This information is needed as a reference for external 32 MHz crystal tuning.

Hi

The Cpin should have as little variation as possible, so it's safe to set Cpin in this formula to 3.1pF. Is there a specific reason you need the upper/lower limits?

Best regards,

Simon

Thank you for reply.

Understood. Since the variation is small, it means we don’t need to worry about the upper and lower limits, correct.

best regards,
