LMKDB1104: Different output impedance

Hailiang Zhang

Part Number: LMKDB1104

Hi Team,

Can I know which typical applications use 100ohm differential impedance and which applications use 85ohm differential impedance?

Regards,

Hi Hailiang,

85Ohms is the current PCIe standard characteristic impedance, but older PCIe generations had 100Ohm impedance. The appropriate impedance depends on the customer's board stackup.

Thanks,

Michael
