Optional ADSP-BF537 EZ-KIT Lite Interfaces

The EZ-KIT Lite and extender must not be powered via the 7.5V supply when in Power-over-Ethernet (PoE) mode. A user can make the appropri- ate jumper changes to the EZ-KIT Lite and extender and then connect the kit to the extender to power both boards via the switch or Midspan device. The user must use a switch or Midspan device that supports power via the data pairs. If a user uses a Midspan device that powers only over the spare pins, then the PoE circuitry will not work.

Table 1-3shows a recommended Midspan device that supports both power over the spare pins and power over the data pairs.

Use the Ethernet connector on the EZ-KIT Lite for the PoE application. Power-over-Ethernet does not work properly if the Ethernet connector is used on the extender board. When in PoE mode, the blinking LEDs (LED1–6]) confirm successful power-up. Since PoE is intended as a simple demonstration of the power circuitry, you are not able to bring up a Visu- alDSP ++ session while in the PoE mode.

Refer to “Power Select Jumper (JP1)” on page 2-4 for the extender’s PoE settings. Refer to the ADSP-BF537EZ-KIT Lite Evaluation System Manual for the EZ-KIT Lite’s PoE settings.

MII Interface

The Media Independent Interface (MII) allows you to evaluate different PHY devices with the ADSP-BF537 EZ-KIT Lite. A separately purchased PHY evaluation board connects directly to the USB-LAN EZ-Extender. You also need to purchase the J2 connector and solder it to be able to con- nect the two boards together. The part numbers of the SMSC’s evaluation boards and J2 connector are shown in Table 1-4.
