KSZ8862-16MQL

Controllers Overview

The KSZ8862-16MQL is a two-port Ethernet switch with non-PCI CPU interface and fiber support, manufactured by Microchip Technology. It operates on a single 3.3V supply within the commercial temperature range of 0°C to +70°C. The device features an integrated Layer-2 switch compliant with IEEE 802.3u standards, supporting 10/100BASE-T/TX on Port 2 and 10/100BASE-FL/FX/SX on Port 1. It utilizes a 1K entry forwarding table and store-and-forward architecture for packet delivery. The component is housed in a 128-pin PQFP package and supports 8-bit or 16-bit generic host processor interfaces.

Controllers Feature Summary

• Supports fully managed switching capabilities including VLAN tagging, QoS prioritization, and IGMP snooping.
• Integrates LinkMD cable diagnostic technology for fault detection and distance measurement.
• Includes dynamic buffer memory scheme designed to minimize image jitter in video applications.
• Provides comprehensive monitoring through port mirroring, sniffing, and MIB counters.

Controllers Applications

• Video Distribution Systems
• High-End Cable, Satellite, and IP Set-Top Boxes
• Voice over IP (VoIP) and Analog Telephone Adapters
• Industrial Control Sensor Devices

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm bus width compatibility. Ensure the procurement documentation matches the exact part number KSZ8862-16MQL to guarantee the correct 128-pin PQFP package and 8/16-bit interface configuration. Cross-reference the revision history for any errata sheets that may apply to the silicon version being ordered.

Controllers Selection Notes

Select this component when a managed two-port switch with fiber connectivity is required for latency-critical embedded applications. The -16 suffix indicates support for 8-bit or 16-bit bus interfaces; choose the -32 variant if a 32-bit interface is necessary. Confirm that the commercial temperature range meets the environmental requirements of the target system design.

Controllers Part Context

This component belongs to the KSZ8862M series, which represents the industry's first fully managed two-port switches with non-PCI CPU interfaces and fiber support. The series is based on a fourth-generation integrated Layer-2 switch architecture. The KSZ8862-16MQL specifically denotes the version optimized for 8-bit or 16-bit host processor connections.
