3 Hardware Description
The KSZ8463ML/RL Evaluation board is a small form-factor board (5.2” x 4.75”) with two10/100 RJ-45
ports and one MII/RMII port. There are two methods for configuring the KSZ8463: Strap-in configuration
and serial interface.
Strap-in mode configuration occurs at power-on (and hardware reset) where the voltage level on certain
pins is automatically sampled and used to configure various features in the device. This is accomplished
with on-board jumper options, so that the KSZ8463 powers up in the desired modes. With no additional
programming of registers, the device will start operation as an unmanaged 3-port switch.
The KSZ8463ML/RL has a serial interface which can be either SPI or MIIM (MDIO/MDC). Normally the
SPI interface is used because it provides read/write access to all KSZ8463 registers. In comparison, the
MIIM interface provides access only to the basic PHY registers in the KSZ8463. Full register access is
required for managed operation of the switch, and to utilize the advanced features such as IEEE 1588
PTP. Access to the SPI interface is provided on the 6-pin header J5. SPI (or MIIM) access is also
provided via the onboard USB port interface. An FT2232D chip is used for the USB-to-SPI/MIIM interface.
Configuration options are explained in detail in the following sections. Figure 1 is a picture of the
KSZ8463ML/RL Evaluation board.
