General Description

The KSZ8765CLX is a highly integrated, Layer 2-

managed, five-port switch with numerous features

designed to reduce overall system cost. It is intended for

cost-sensitive applications requiring four 10/100Mbps

copper ports and one 10/100/1000Mbps Gigabit uplink

port. The KSZ8765CLX incorporates a small package

outline, the lowest power consumption with internal

biasing, and on-chip termination. Its extensive set of

features include enhanced power management,

programmable rate limiting and priority ratio, tagged and

port-based VLAN, port-based security and ACL rule-based

packet filtering technology, QoS priority with four queues,

management interfaces, enhanced MIB counters, high-

performance memory bandwidth, and a shared memory-

based switch fabric with non-blocking support. The

KSZ8765CLX provides support for multiple CPU data

interfaces to effectively address both current and emerging

fast Ethernet and Gigabit Ethernet applications where the

Port 5 GMAC can be configured to any of the GMII,

RGMII, MII, and RMII modes.

The KSZ8765CLX product is built upon Micrel’s industry-

leading Ethernet’s latest analog and digital technology,

with features designed to offload host processing and

streamline the overall design.

 Two integrated MAC/PHYs 100Base-FX on Port 1 and

Port 2

 Two integrated MAC/PHYs 10/100Base-T/TX on Port

3 and Port 4

 One integrated 10/100/1000Base-T/TX GMAC with

selectable GMII, RGMII, MII, and RMII interfaces

 Small 80-pin LQFP package

A robust assortment of power management features

including energy-efficient Ethernet (EEE), power

management event (PME), and wake-on-LAN (WoL) have

been designed in to satisfy energy efficient environments.

All registers in the MAC/PHY units can be managed

through the SPI interface. MIIM PHY registers can be

accessed through the MDC/MDIO interface.
