KSZ8841-16MVLI

Controllers Overview

The KSZ8841-16MVLI is a single-port Fast Ethernet MAC controller with a non-PCI CPU interface, compliant with IEEE 802.3u standards. It supports 10BASE-T and 100BASE-TX speeds with auto-negotiation for full- and half-duplex modes. The device features an 8-bit or 16-bit generic host processor interface, 8 KB of internal memory for RX/TX FIFO buffers, and HP Auto MDI-X capability. It operates on a single 3.3V power supply with 5V tolerant I/O buffers and includes LinkMD cable diagnostics and Wake-on-LAN functionality. The industrial temperature grade version functions within a range of -40°C to +85°C.

Controllers Feature Summary

• Supports flexible 8-bit and 16-bit generic host processor interfaces for embedded applications.
• Integrates dynamic buffer memory scheme to minimize latency and prevent image jitter in video over IP applications.
• Includes LinkMD cable diagnostic capabilities to determine cable length and detect open or short conditions.

Controllers Applications

• Video Distribution Systems
• High-End Cable, Satellite, and IP Set-Top Boxes
• Industrial Control in Latency-Critical Applications

Controllers Procurement Notes

Verify the specific ordering suffix MVLI confirms the industrial temperature range (-40°C to +85°C) and the 16-bit bus interface configuration. Ensure compatibility with the required 25 MHz reference clock source and confirm that the LQFP-128 package aligns with the target PCB footprint design constraints.

Controllers Selection Notes

Select this component when a single-port Ethernet solution with a non-PCI interface is required for industrial environments. It is suitable for systems needing low-latency performance and integrated PHY/MAC functionality without PCI bus overhead. Consider the 8/16-bit bus width options based on the host processor's available data lines.

Controllers Part Context

This part belongs to the KSZ8841M series of single-port Ethernet MAC controllers. It is designed as a mixed analog/digital device offering Wake-on-LAN technology. The M-series specifically denotes non-PCI CPU interface chips, distinguishing it from the KSZ8841P series which utilizes a PCI interface.
