1 USB-LAN EZ-EXTENDER INTERFACES This chapter provides the setup procedures for both the Blackfin USB-LAN EZ-Extender and EZ-KIT Lite (ADSP-BF533, ADSP-BF537 or ADSP-BF561) and describes each of the interfaces the extender supports. The information is presented in the following order. •...
USB-LAN EZ-Extender Setup 3. Remove any rubber feet that may be attached to the EZ-KIT Lite. In place of these rubber feet, install the four nylon feet and screws provided with the USB-LAN EZ-Extender. Install the nylon feet in the mounting holes of the EZ-KIT Lite’s printed circuit board (PCB).
USB-LAN EZ-Extender Interfaces Ethernet Software For information on the LAN software, refer to the file located in the LAN Software Readme.txt ...\VisualDSP++ install path\Blackfin\EZ-KITs\USB-LAN EZ-EXTENDER\ directory. USB 2.0 Interface The USB-LAN EZ-Extender allows you to connect a USB 2.0 chip to a Blackfin processor without any other programmable logic required.
You can reset the Ethernet processor by asserting the board reset on the ADSP-BF533 and ADSP-BF561 EZ-KIT Lites. The reset connects to a supervisory reset circuit managed by the Analog Devices ADM708 IC device. ADM708 also asserts a reset to the Ethernet chip at power-up.
USB-LAN EZ-Extender Interfaces EZ-KIT Lites are described in the file in the LAN Software Readme.txt subdirectory of the ...\Blackfin\Examples\USB-LAN EZ-EXTENDER\LAN VisualDSP++ installation directory. The readme file describes the LAN software, source code, drivers, and explains how to run an Ethernet application.
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.

2 USB-LAN EZ-EXTENDER HARDWARE REFERENCE This chapter describes the hardware design of the USB-LAN EZ-Extender. The following topics are covered. • “System Architecture” on page 2-2 Describes the configuration of the extension board and explains how the board components interface with the processor and EZ-KIT Lite.
USB-LAN EZ-Extender Hardware Reference Jumper Setting Before using the Blackfin USB-LAN EZ-Extender, follow the steps in “USB-LAN EZ-Extender Setup” on page 1-1. Figure 2-2 shows the locations of all jumper headers. A two-pin jumper can be placed on the respective jumper header for different functionality. The following sections describe all possible jumper settings and associated functionality.

USB-LAN EZ-Extender Hardware Reference LAN Power Jumper (JP2) The LAN power jumper, , is used to power the SMSC’s 91C111 device with 3.3V. By default, and, in general, the jumper is plugged in. This jumper is provided for user flexibility. The user must make changes to the jumper only when no power is applied to the USB-LAN EZ-Extender and/or the EZ-KIT Lite.
Switch Settings Switch Settings Before using the Blackfin USB-LAN EZ-Extender follow the steps in “USB-LAN EZ-Extender Setup” on page 1-1. Figure 2-3 shows the locations of all switches. The following sections describe all possible switch settings and associated functionality. Figure 2-3.
