Tool/software:
We are Re-evaluating the PCB routing of a system based on TMS320DM8168CCYGA2 and need to understand the length matching constraints required for GMII TX and RX pairs as well as any specific layout guideline is present regarding GMII interface.
Hi,
We don't have a specific GMII layout guideline but I hope you find this general high speed layout guideline useful. https://www.ti.com/lit/pdf/spraar7.
