KSZ8842-16MVL-TR

Controllers Overview

The KSZ8842-16MVL-TR 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 an 8/16-bit generic host processor interface and includes two 10/100 transceivers, two MAC units, and a DMA channel. It utilizes a single 3.3V power supply and operates within a commercial temperature range of 0°C to +70°C. The component is housed in a 128-pin LQFP package.

Controllers Feature Summary

• Supports advanced Layer-2 management including VLAN tagging, QoS prioritization, and spanning tree protocol.
• Configurable as a low-latency repeater for latency-critical embedded or industrial applications.
• Includes LinkMD cable diagnostic capabilities to determine cable length and diagnose faults.

Controllers Applications

• Video over IP systems
• Industrial control sensor devices
• Security and surveillance cameras

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature grade. Ensure the host system provides the required 8/16-bit bus interface signals. Confirm that the commercial temperature range meets the operational requirements of the target environment before finalizing procurement.

Controllers Selection Notes

Select this model when a non-PCI CPU interface is required for a two-port Fast Ethernet application. The -16 suffix indicates support for 8-bit or 16-bit bus widths. Verify compatibility with the host processor's address decoding and timing constraints. Consider the -MVLI variant if an extended industrial temperature range is necessary for the deployment.
