Introduction
The KSZ8463ML/RL Evaluation Board provides a platform for testing or exploring the functionally of the
KSZ8463ML and KSZ8463RL IEEE 1588 Precision Time Protocol (PTP) enabled switch products.
The KSZ8463ML, KSZ8463FML, KSZ8463RL and KSZ8463FRL devices are highly integrated 2-port
10BASE-T / 100BASE-TX/FX managed Ethernet switches with MII and RMII interface connectivity to a
host on Port 3. They are the ideal solution in industrial applications where real time clock synchronization
using Ethernet connectivity across a network is desired. The KSZ8463ML/RL includes all the functions of
a 10/100BASE-T/TX/FX switch system that combines switch engine, frame buffers management,
addresses look-up table, queue management, MIB counters, media access controllers (MAC) and PHY
transceiver interfaces. The KSZ8463ML/RL is fully compliant with the IEEE 1588 (Version 2) Precision
Time Protocol and IEEE 802.3 standards (10BASE-T and 100BASE-TX/FX). The KSZ8463ML/FML
devices have Port 3 configured for MII mode, while the KSZ8463RL/FRL devices have Port 3 configured
for RMII mode.
This KSZ8463ML/RL Evaluation Board User Guide provides the information necessary to configure and
set up the board to evaluate or test the KSZ8463ML and KSZ8463RL devices in different environments.
