We’re having some issues with the 25MHz crystal circuit for the DP83TC812S-Q1. We are having issues with the crystal being over driven. The EVM has a 1kΩ series R on the XO pin. We’ve tested that value and are still seeing the crystal being over driven. 1kΩ also seems large. Is there some history behind this? Is this something TI has had issues with?
We are using the same crystal as the TI EVM (ECS-250-12-33Q-JES-TR).
