KSZ8842-PMBL-AM

Controllers Overview

The KSZ8842-PMBL-AM is a two-port Ethernet switch with a PCI interface, manufactured by Microchip Technology. It operates at data rates of 10 Mb/s and 100 Mb/s, supporting IEEE 802.3u standards. The device features a 32-bit/33 MHz PCI processor interface, two 10/100 transceivers, three MAC units, and a non-blocking switch fabric. It utilizes a 1K entry forwarding table and on-chip frame buffer memory. The component is available in a 100-ball LFBGA package and supports both commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature ranges.

Controllers Feature Summary

• Fully managed Layer-2 switch with VLAN support for up to sixteen groups and QoS priority management.
• Low-latency repeater mode capability for latency-critical embedded or industrial applications.
• Integrated LinkMD cable diagnostics for fault detection and distance measurement.
• Supports Jumbo frames up to 1916 bytes and dynamic buffer memory schemes.

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 documentation to confirm package type and temperature grade. Ensure compatibility with the host system's PCI bus requirements and power supply specifications before procurement.

Controllers Selection Notes

Select this component for applications requiring a fully managed two-port switch with a direct PCI interface. Consider the PMBL variant for space-constrained designs utilizing the LFBGA package. Verify that the required operating temperature range aligns with the commercial or industrial grade availability.

Controllers Part Context

The KSZ8842-PMBL-AM belongs to the KSZ8842 series of two-port Ethernet switches. This series includes variants with both PCI and non-PCI CPU interfaces. The PMBL designation specifically indicates the LFBGA package option within the PCI interface family.

Controllers Replacement Considerations

Consult the official datasheet for confirmed substitute part numbers. Cross-reference pinouts and electrical characteristics when considering alternative components from other manufacturers.
