KSZ8842-16MVL

Controllers Overview

The KSZ8842-16MVL is a two-port Ethernet switch with a non-PCI CPU interface, designed for embedded and industrial applications. 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 with HP Auto-MDIX. It utilizes a single 3.3V power supply and operates within a temperature range of -40°C to +85°C. The component is housed in a 128-pin LQFP package.

Controllers Feature Summary

• Fully managed Layer-2 switching with VLAN support and QoS prioritization
• Configurable as a low-latency repeater or standard switch
• Integrated LinkMD cable diagnostic capabilities
• Supports dynamic buffer memory for video over IP applications

Controllers Applications

• Video Distribution Systems
• Industrial Control in Latency Critical Applications
• 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 datasheet to confirm pin compatibility and electrical specifications. Ensure the selected variant matches the required bus width and operating temperature range for the target application environment.

Controllers Selection Notes

Select this model when an 8/16-bit parallel interface is required instead of a 32-bit bus. Confirm that the system design accommodates the 128-pin LQFP package dimensions and thermal requirements. Validate that the host processor can support the necessary control registers and interrupt handling mechanisms.

Controllers Part Context

This component belongs to the KSZ8842 series of two-port Ethernet switches. It serves as a fully managed solution for Fast Ethernet networks, offering advanced features such as spanning tree protocol support and multicast filtering. The series includes variants with different bus widths and temperature grades to suit various deployment scenarios.

Controllers Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the same series. Verify that any substitute part maintains the same 8/16-bit interface configuration and industrial temperature rating.
