KSZ8893FQL

Controllers Overview

The KSZ8893FQL is a single-chip 3-port Fast Ethernet switch designed for fiber support applications. It integrates three MAC units and two PHYs compliant with IEEE 802.3u standards, featuring a non-blocking switch fabric and store-and-forward architecture. Port 1 supports 10BASE-FL, 100BASE-SX, or 100BASE-FX fiber modes, while Ports 2 and 3 support 10/100BASE-T/TX copper. The device operates on a 1.2V core voltage and 3.3V I/O/transceiver supply, housed in a lead-free 128-pin PQFP package.

Controllers Feature Summary

• Integrated TS-1000 V2 OAM sub-layer for center-to-terminal communication
• Supports comprehensive Layer 2 management features including VLAN and QoS
• Includes LINKMD TDR-based cable diagnostics for copper ports
• Provides multiple CPU control interfaces including SPI, I2C, and SMI

Controllers Applications

• Media Conversion Modules (10BASE-FL to/from 10BASE-T)
• FTTx Managed/Unmanaged Media Converters
• Fiber Broadband Gateways

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product identification system to ensure correct package and temperature grade. Confirm RoHS compliance status and check for any active engineering change notices that may affect pinout or electrical characteristics prior to final design approval.

Controllers Selection Notes

Select this component when fiber connectivity is required on one port alongside standard copper Ethernet ports. Ensure the host processor supports the desired management interface (SPI, I2C, or SMI). Verify that the application environment falls within the specified commercial operating temperature range of 0°C to +70°C.

Controllers Part Context

This part belongs to the KSZ8893 series of highly integrated Layer 2 managed switches. It is specifically differentiated by its fiber port capabilities, making it suitable for media conversion tasks where copper-to-fiber translation is necessary within a compact single-chip solution.
