1 SMII Output. Low for SMII, high for RMII. Disregard this signal for single-mode DUTs.
2 BRDCON Input. Active low, DUT connected flag. It should be tied to ground at the DUT.
3 R_CLK+/– and R_SYNC+/–. These two LAN-3150A LVDS input pairs should be the output of 65LVDS31 drivers on the DUT. These signals must be
supplied to LAN-3150A via J2.
4 RESET This LAN-3150A output, low active, can be used as PHY hardware reset signal.
5 DNC Do not connect.
6 MDIO This signal is bidirectional.
MDC This is an output signal.
For a single eight-port DUT, the above MII management signals from the J2 connector should be used; the corresponding signal at the J1 connector should be
ignored.
