KSZ8895FQXC

Controllers Overview

The KSZ8895FQXC is a Layer 2 managed, five-port Ethernet switch integrated with four 10/100Base-T/TX transceivers and one 100Base-FX transceiver on Port 4. It operates within a voltage range of 1.8 V to 3.3 V and supports data rates of 10 Mb/s and 100 Mb/s. The device utilizes a 128-pin PQFP package and provides MII and RMII interfaces for CPU connectivity. It features a non-blocking shared memory switch fabric with 1.4 Gbps bandwidth and includes comprehensive management capabilities via SPI, I2C, and SMI interfaces.

Controllers Feature Summary

• Integrated five-port architecture combining copper and fiber physical layer transceivers
• Layer 2 managed switching with VLAN tagging, QoS prioritization, and rate limiting
• Dual interface support on Port 5 allowing simultaneous MAC and PHY connection options
• Comprehensive monitoring including port mirroring, loopback diagnostics, and MIB counters

Controllers Applications

• VoIP Phone systems
• Industrial Control networks
• IPTV Point of Presence (POF) equipment
• Broadband Gateway and Firewall devices

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product identification system to ensure correct package type and temperature rating. Confirm that the component matches the required commercial or industrial operating specifications before finalizing procurement orders.

Controllers Selection Notes

Select this model when a mixed copper and fiber port configuration is required within a single managed switch solution. Ensure the design accommodates the 128-pin PQFP footprint and supports the necessary 1.2V core and 3.3V I/O power domains. Verify compatibility with the host processor's MII or RMII interface requirements.

Controllers Part Context

This component belongs to the KSZ8895 family of integrated switches. The FQX variant specifically distinguishes itself by providing four twisted-pair ports and one fiber optic port, unlike the MQX which offers all copper ports. This configuration targets applications requiring long-distance fiber uplinks alongside standard copper connections.
