KSZ8842-32MQL

Controllers Overview

The KSZ8842-32MQL is a fully managed, two-port Ethernet switch with a non-PCI CPU interface. It supports IEEE 802.3u standards and operates at data rates of 10 Mb/s and 100 Mb/s. The device features a 32-bit generic host processor interface and includes two 10/100 transceivers with HP Auto-MDIX. It utilizes a single 3.3V power supply within a voltage range of 3.1 V to 3.5 V. The component is housed in a PQFP-128 package and functions within a commercial temperature range of 0°C to +70°C.

Controllers Feature Summary

• Fully managed Layer-2 switching capabilities including VLAN support, QoS prioritization, and spanning tree protocol.
• Configurable as a low-latency repeater or switch with dynamic buffer memory for video applications.
• Integrated LinkMD cable diagnostic functionality for fault detection and distance measurement.
• Supports comprehensive monitoring via port mirroring, sniffing, and MIB counters.

Controllers Applications

• Video Distribution Systems
• Industrial Control in Latency Critical Applications
• Security and Surveillance Cameras

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm pin compatibility and electrical specifications. Ensure the procurement documentation matches the exact part number to avoid discrepancies in bus width or package type. Cross-reference the revision history for any errata that may impact system integration.

Controllers Selection Notes

Select this component when a non-PCI interface is required for embedded or industrial Ethernet designs. The 32-bit bus variant is suitable for high-throughput host processors. Consider the commercial temperature rating for standard indoor environments rather than harsh industrial conditions requiring extended ranges.

Controllers Part Context

This part belongs to the KSZ8842 series of two-port switches. It is distinguished from PCI interface variants by its generic host bus connectivity. The -32 suffix specifically denotes the 32-bit bus architecture, differentiating it from 8/16-bit versions like the KSZ8842-16MVLI.

Controllers Replacement Considerations

The KSZ8842-16MVLI serves as a functional alternative but utilizes an 8/16-bit bus interface instead of the 32-bit interface found in the KSZ8842-32MQL. Verify host processor compatibility before substitution.
