NXP Semiconductors SJA1105SMBEVM UM 1. Introduction The SJA1105SMBEVM (SJA1105S Mother Board Evaluation Module, see Fig 1) is designed for evaluating the capabilities of the SJA1105P/Q/R/S Automotive Ethernet switch family and the TJA1102 Automotive Ethernet PHYs, by developing and running customer software. Therefore, the board features the MPC5748G MCU with a rich set of peripherals for communication and automotive applications. -

4. Hardware Description 4.1 Power The SJA1105SMBEVM is powered by a single 12 Volt input. It is advised to use an adapter that can deliver at least 1 Amp for covering startup current peaks and full-load situations. The nominal current is ~350mA@12V and depends on the number of active PHYs, and if the port is connected to a peer. -

ProcessorExpert in the ENET device driver. o For 100BASE-T1 ports, the Link LED indicates an established link. All 100BASE-T1 ports on the SJA1105SMBEVM take the master role, so the peers must be configured for slave, so that a link can come up.
