DP83620: Alternative to DP83630?

Part Number: DP83620
Other Parts Discussed in Thread: DP83630

Hi Experts,

Good day.

Due to stock issue, client would want to use DP83620 over DP83630 on their existing design.

They are concerned more about the GPIOs 3 & 4; those two pins are connected another DP83630's GPIOs 3 & 4.

The DP83620 states that those two pins are reserved pins and should not be connected to any other logic. The software application does not use the IEEE1588 features which would utilize those pins.

Their question is if there is any issue involved to connect the pins 23 & 25 of one DP83620 to another DP83620? Is there a possibility that this connection can lead to a problem?

Thanks for your guidance.
