Hi team

I need the overshoot and undershoot values for DP83620SQ/NOPB 's clock connected at X1 pin

also can you give me the VIH (max) and VIL(min)??


Best regards,
William

    Hi William,

    The overshoot/undershoot values are located on Table 4.2 of the datasheet. Depending on the supply voltage, you will either have a +/- 10% or 5% wiggle room.

    Regarding VIH and VIL, there is no VIH max or VIL min as these are the thresholds where the PHY recognizes a signal as high or low. To recognize a high, the signal must be above 2V, but should not exceed the I/O supply voltage. To recognize a low, the signal must be below 0.8 (3.3V I/O supply) or 0.7 (2.5 I/O supply) and should not be lower than GND.

    Sincerely,

    Gerome
