DP83822I: Oscillator : Pull-down Resistor for XI

Hello Nagata,

I will look for the resistance value and get back. But do you have clock coming up after supply stablization? This may be required only for that case.

Vikram,

Yes, I would like to care the case which clock comes after power supply.

Could you please let me know the resistance value?

Regards,
Nagata.

Hi, Vikram,

Thank you for your support.

If clock isn't delayed, will the device have trouble when pull -down register is attached in XI?

Nagata.

Vikram -san,

Here is additional question for pull-down register. My customer already evaluated with Pull down register = 2.2K ohm.

Is there a issue or concern if he use 2.2K ohm?

Regards,
Nagata.

Hello Nagata,

Kindly share the waveform at XI pin. We can have look at it and sign-off.

2.2Kohms means that oscillator will have to support higer load current. Hence we should look at waveforms once.
