17、s, and enables the RGMII signals to be wired for the following two usages: RGMII Loop Back RGMII Connection to GMAC 4.5.1 RGMII Loop Back The KSZ9031RNX-EVAL board is shipped with the RGMII signals configured for RGMII Loop Back. Resistors R14, R16, R136-R139 are populated to connect the RGMII outpu
18、t clock and signals to their respective RGMII input clock and signals, thru resistors R18, R17, R143, R142, R141, R140, respectively. Refer to KSZ9031RNX-EVAL Board Schematic for details. RGMII Loop Back enables the KSZ9031RNX device to operate as a standalone evaluation platform without the need of
19、 an external GMAC. Ethernet traffic from the link partner (Spirent SmartBits 6000B in the following figure) are received by the KSZ9031RNX device, looped back externally via RGMII pins, and transmitted back to the link partner. Figure 2. KSZ9031RNX-EVAL Board RGMII Loop Back RGMII Loop Back is suppo
20、rted for 1000Base-T and 100Base-TX only. 10Base-T requires a MAC due to preamble consumption, and therefore is not supported. KSZ9031RNX-EVAL Board Users Guide Micrel, Inc.
