Gigabit PoE đảm bảo EMC

Contents:

• EMC behavior of the Gigabit Ethernet interface.
• Basic EMC considerations of Power-over-Ethernet: EMC test setup, operating parameters, influence of output voltage, output filter, influence of different load resistors, input filter, optimization of conducted emissions, noise immunity.
• EMC performance of reference design: conducted emission (CISPR 32), radiated emission (CISPR 32), radiated immunity (IEC 61000-4-3) / against burst (IEC 61000-4-4) / against surge (IEC 61000-4-5) / against continuous conducted disturbances (IEC 61000-4-6)
• EMC improvements: Island concept
