4.0 Hardware Description
The KSZ8795-POE-EVAL evaluation board is in a compact form factor and can sit on a bench near
a computer with USB connector. There are two options for configuration: strap in mode; SPI mode
and Strap-in mode that is easily done with on board jumper options. SPI mode is accomplished
through a built in USB port interface. You can configure the KSZ8795 device on board by the USB
port. Using Micrel SPI software and your PC, you can access the KSZ8795’s full feature set
registers by the USB to SPI interface. The board also features RGMII to hook up a KSZ9031RNX
as a Gigabit uplink for Gigabit port 5.
The KSZ8795-POE-EVAL evaluation board is easy to use. There are programmable LED
indicators for link and activity on all ports and a power LED. A manual reset button allows the user
to reset the board without removing the power plug. A standard 12VDC power supply can be used
by the power jack so that the user can supply power from any 110-240 Volt AC wall or bench
socket.
