8.2.2.1.1
SGMII Layout Guidelines
All SGMII connections must be AC-coupled through an 0.1µF capacitor. Series capacitors must be 0.1µF and the size must be 0402 or smaller.
SGMII signals are differential signals.
Traces must be routed with 100Ω differential impedance.
Skew matching within a pair must be less than 5pS, which correlates to 30 mil for standard FR4.
There is no requirement to match the TX pair to the RX pair.
SGMII signals must be routed on the same layer.
Pairs must be referenced to parallel ground plane.
When operating in 6-wire mode, the RX pair must match the Clock pair to within 5pS, which correlates to 30 mil for standard FR4.
