Pairing PHY chips with Gigabit network transformers is less “universal” than I expected

Pairing PHY chips with Gigabit network transformers is not as universal as expected, causing stability issues rather than link-up problems. This affects Gigabit Ethernet hardware development. Engineers should validate multiple transformer vendors and prioritize stability over simple interoperability. This is crucial for engineers working on Gigabit Ethernet hardware. Engineers should also consider EMI and stability issues during development.
