KSZ8842-16MBLI

Controllers Overview

The KSZ8842-16MBLI 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 bus interface and includes two 10/100 transceivers with HP Auto-MDIX. It utilizes a single 3.3V power supply and operates within an industrial temperature range of -40°C to +85°C. The component is housed in a 100-ball LFBGA package.

Controllers Feature Summary

• Supports advanced Layer-2 management functions including VLAN tagging, QoS prioritization, and IGMP/MLD snooping for multicast filtering.
• Features a low-latency repeater mode capable of cut-through switching for latency-critical embedded applications.
• Includes LinkMD cable diagnostic technology to determine cable length and identify faults.
• Provides comprehensive monitoring capabilities such as port mirroring, sniffing, and MIB counters for statistics gathering.

Controllers Applications

• Video over IP systems
• Industrial control in latency-critical applications
• Motion control systems
• 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 compatibility with the required bus width and voltage levels before finalizing procurement. Cross-reference the datasheet revision to confirm pinout consistency.

Controllers Selection Notes

Select this model when an industrial temperature range and an 8/16-bit parallel interface are required. Compare against the 32-bit variant if higher bandwidth is needed or the PCI version if a different host interface is preferred. Confirm that the LFBGA package fits the target PCB layout constraints.

Controllers Part Context

This component belongs to the KSZ8842 series of two-port Ethernet switches. It represents the non-PCI CPU interface variant designed for general-purpose host processors. The 'M' designation indicates the non-PCI interface, while '16' specifies the 8/16-bit bus support.

Controllers Replacement Considerations

Consult the official datasheet for parameter-equivalent alternatives. Verify that any substitute maintains the same package dimensions, pinout, and electrical characteristics to ensure mechanical and functional compatibility.
