4.2 SGMII/Fiber Interface

SGMII Pins from the DUT are multipurpose pins functioning as SGMII and Fiber IO pins. By default, the EVM is configured for Fiber operation.

Note: Fiber Transceiver is not a part of the EVM package. SFP cage and SFP connector need to be mounted.

For routing signals to Fiber Transceiver, populate R31, R38, R45, and R47. Remove C12, C14, C15, and C17.

For routing signals to SGMII SMAs, populate C12, C14, C15, and C17. Remove R31, R38, R45, and R47.
