DP83867IS: XI Clock Input thresholds

Jason Snow

Part Number: DP83867IS

What are the VIH and VIL thresholds for the XI clock input when using an XO? Are they dependent on VDDIO and align with the specs as per Section 7.5 of the datasheet?

    Hi Jason,

    I want to confirm that you are asking about using an external crystal oscillator on the XI and XO pins of the device. There are no VIH/VIL thresholds for a crystal oscillator nor any VDDIO dependency. 

    Please follow the crystal recommendations section of the datasheet when considering the parameters of a crystal oscillator. 

    Regards,
    Justin
