Device Overview

Summary

The KSZ8795 is a highly-integrated, Layer 2-managed, 5-port switch with numerous features designed to reduce system cost. It is intended for cost-sensitive applications requiring four 10/100Mbps copper ports and one 10/100/1000Mbps Gigabit uplink port.

The KSZ8795CLX incorporates a small package outline, lowest power consumption with internal biasing, and on-chip termination. Its extensive features set includes enhanced power management, programmable rate limiting and priority ratio, tagged and port-based VLAN, port-based security and ACL rule-based packet filtering technology, quality-of-service (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 KSZ8795CLX 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 GMII, RGMII, MII and RMII modes.

The KSZ8795CLX product is built upon Microchip's industry-leading Ethernet latest analog and digital technology, with features designed to offload host processing and streamline your overall design.
   
- Four integrated 10/100Base-T/TX MAC/PHYs
- 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), PME, and wake-on-LAN (WoL) have been designed-in to satisfy energy-efficient environments. All registers in the MAC and PHY units can be managed through the SPI interface. MIIM PHY registers can be accessed through the MDC/MDIO interface.

Microchip's complimentary and confidential LANCheck® online design review service is available for customers who have selected our products for their application design-in. The LANCheck online design review service is subject to Microchip's Program Terms and Conditions and requires a myMicrochip account.
