KSZ8895FQXCA

Controllers Overview

The KSZ8895FQXCA is a Layer 2 managed, five-port Ethernet switch manufactured by Microchip Technology. It integrates four 10/100Base-T/TX transceivers and one 100Base-FX transceiver on Port 4. The device features a non-blocking shared memory switch fabric with 1.4 Gbps bandwidth and 64 Kbyte frame buffering. It supports IEEE 802.3u standards, MII/RMII interfaces on Port 5, and comprehensive management via SPI or SMI. Operating temperatures range from 0°C to +70°C in a 128-pin PQFP package.

Controllers Feature Summary

• Integrated five-port switching architecture with four copper and one fiber physical layer transceivers
• Layer 2 managed capabilities including VLAN tagging, QoS prioritization, and RSTP support
• Dual interface configuration on Port 5 supporting separate MAC and PHY connections via MII/RMII
• Comprehensive register access through high-speed SPI and I2C master interfaces

Controllers Applications

• VoIP Phone systems
• Industrial Control networks
• IPTV Point of Presence (POF) equipment
• SOHO Residential Gateways
• Standalone 10/100 5-Port Switches

Controllers Procurement Notes

Verify the specific suffix 'CA' against official Microchip documentation to confirm exact manufacturing lot or revision details. Ensure compatibility with the 128-pin PQFP footprint during PCB layout. Confirm power supply requirements for the internal 1.2V LDO controller if utilized instead of an external solution.

Controllers Selection Notes

Select this model when a mixed media environment requiring both copper and fiber connectivity is necessary. The FQX variant specifically provides a dedicated 100Base-FX port, distinguishing it from MQX and RQX families. Verify that the commercial temperature range meets the operational environment constraints.

Controllers Part Context

This component belongs to the KSZ8895 family of integrated switches. The FQX designation indicates the inclusion of a fiber optic transceiver on Port 4, whereas MQX includes all copper ports and RQX utilizes RMII interfaces exclusively. All variants share the same core switching fabric and management features.
