KSZ8841-16MVL

Controllers Overview

The KSZ8841-16MVL 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 dynamic buffer memory management. It operates on a single 3.3V power supply with 5V tolerant I/O buffers and includes HP Auto MDI-X capabilities. The component supports Wake-on-LAN functionality and LinkMD cable diagnostics.

Controllers Feature Summary

• Integrated 10/100 Mbps physical layer transceiver with adaptive equalizer and baseline wander correction
• Flexible 8-bit and 16-bit generic host processor bus interface supporting burst data transfers
• Dynamic buffer memory scheme designed to minimize image jitter in video applications
• LinkMD cable diagnostic capability for determining cable length and identifying faults

Controllers Applications

• Video Distribution Systems
• High-End Cable, Satellite, and IP Set-Top Boxes
• Voice over IP (VoIP) and Analog Telephone Adapters
• Industrial Control in Latency-Critical Applications
• Security and Surveillance Cameras

Controllers Procurement Notes

Verify the specific package type and temperature grade against the datasheet before ordering. Confirm that the host system provides the required 25 MHz reference clock and compatible 8-bit or 16-bit bus timing. Ensure power supply decoupling meets the recommended layout guidelines for stable operation.

Controllers Selection Notes

Select this model when a non-PCI interface is required for a single-port Ethernet connection. Choose between commercial and industrial temperature ranges based on environmental conditions. Verify that the host processor supports the necessary synchronous or asynchronous bus protocols defined in the interface specifications.

Controllers Part Context

This component belongs to the KSZ8841 series of single-port Ethernet MAC controllers. It is distinct from the KSZ8842 series, which offers two ports, and the KSZ8841P, which utilizes a PCI interface instead of a generic CPU bus. The 'M' suffix denotes the non-PCI variant, while 'VL' indicates the LQFP-128 package and commercial temperature range.

Controllers Replacement Considerations

For direct pin-compatible replacements within the same family, consider the KSZ8841-32MVL for 32-bit interface requirements. For industrial temperature grades, the KSZ8841MVLI is available. Cross-family migration to the KSZ8842 requires interface redesign due to port count differences.
