Micro-Jumper/Resistor Options for eTSEC1
Figure 35
shows the graphical representation for Setup 4.
Figure 35. Setup 4 Resistor Options for REVA1
Because the eTSEC1 Ethernet switch PHY on the RDB supports only RGMII, the eTSEC1 SGMII is not
supported on the RDB. The resistor options listed only matter for the eTSEC1 pin connections. They have
nothing to do with switching between eTSEC2 RGMII and SGMII. They are listed for reference. The
switch between eTSEC2 RGMII and SGMII does not require hardware modification on the RDB.

REVB Boards
For REVB boards, three more resistor options (R311–R313) are added to route three IEEE 1588 signals
to the IEEE 1588 connector.
All other resistor options are the same as on the REVA1 to REVA4 boards.
Table 14
shows how to populate the resistors if these three optional signals are used.
4.4
REVC Boards
For REVC boards, 22 more resistor options (R311–R313) are added to route eTSEC2 RGMII signals either
to L2 Switch or Marvell 88E1111 PHY. All other resistor options are the same as on the REVB boards.
