Hi, we have a product which uses W5500 as the Ethernet controller. But we are running out of stock of the crystal that connects to pin 30 and 31. We see from the datasheet that the requirement for the crystal is 25MHz. Can we use some other frequency like 24MHz (lower) or 30MHz (higher)?
Use of other frequencies is not guaranteed.
The W5500 Ethernet controller is designed to work with a 25 MHz crystal for its Ethernet PHY to operate correctly. Using a crystal with a different frequency can lead to the PHY not operating within its specified parameters, which can cause unreliable operation or even a failure to function.
