KSZ8862-32MQL

Controllers Overview

The KSZ8862-32MQL is a two-port Ethernet switch manufactured by Microchip Technology, designed for non-PCI CPU interfaces with fiber support. It operates on a single 3.3V power supply within a commercial temperature range of 0°C to +70°C. The device features a 1K entry forwarding table and store-and-forward architecture. Port 1 supports 10BASE-FL and 100BASE-SX/FX fiber modes, while Port 2 provides 10/100BASE-T/TX copper connectivity. It utilizes a 128-pin PQFP package and includes an integrated LED driver and post amplifier for optical modules.

Controllers Feature Summary

• Supports IEEE 802.1Q VLAN tagging and removal on a per-port basis
• Includes LinkMD cable diagnostic functionality for fault detection
• Provides four priority queues for handling voice, video, data, and control packets

Controllers Applications

• Video Distribution Systems
• Voice over IP (VoIP) and Analog Telephone Adapters
• Security and Surveillance Cameras

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm interface width and package type. Ensure that the required environmental operating conditions align with the commercial grade specifications. Confirm availability through authorized distribution channels as stock levels fluctuate.

Controllers Selection Notes

Select this component when a managed Layer-2 switch with fiber port capability is required. The 32-bit bus interface version is suitable for high-speed host processor integration. Consider the dynamic buffer memory scheme for applications sensitive to image jitter or latency.

Controllers Part Context

This part belongs to the KSZ8862M family, which represents a fully managed two-port switch with non-PCI CPU interface and fiber support. It is based on a fourth-generation integrated two-layer switch compliant with IEEE 802.3u standards. The -32MQL suffix specifically denotes the 32-bit bus interface variant in a PQFP package.

Controllers Replacement Considerations

The KSZ8862-16MQL serves as a direct alternative offering identical switching capabilities but utilizing an 8-bit or 16-bit generic host processor interface instead of the 32-bit interface found in the -32MQL variant.
