PM6108B-FEI

Overview

The PM6108B-FEI is a member of the META-DX1 family, functioning as a multi-purpose Ethernet MAC/PHY supporting rates from 1 GE to 400 GE. It provides up to 1.2 Tbps capacity using 48 integrated high-speed SerDes configured for PAM4 signaling, or 600 Gbps with NRZ SerDes. The device integrates analog and PCS retiming, forward and reverse gearboxing, crosspoint functionality, and hitless 2:1 multiplexing. It supports IEEE 1588v2 PTP up to Class C/D timestamping and SyncE. Unlike other family members, this specific part does not include integrated MACsec encryption engines.

Feature Summary

• Provides up to 1.2 Tbps throughput via 48 integrated 28G NRZ/56G PAM4 SerDes
• Supports flexible I/O with crosspoint and gearbox functionality for any-to-any connectivity
• Enables hitless 2:1 multiplexing for working/protect switch applications
• Includes line-speed MAC support without integrated hardware encryption engines

Applications

• High-density Ethernet line cards for routers and switches
• Data center, service provider, and enterprise networking equipment
• Working/protect switches requiring hitless mux capabilities
• Ethernet transponders and muxponders

Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors. Confirm package integrity upon receipt, as the unit utilizes a BBGA-1221 surface-mount format. Ensure compatibility with existing system firmware and SDK versions before integration into production environments.

Selection Notes

Select the PM6108B-FEI when high-capacity retiming, gearboxing, and crosspoint features are required without the need for integrated MACsec encryption. This model serves as a cost-effective alternative to the PM6110B-FEI for applications where security is handled externally or is not mandated by the design specifications.

Part Context

This component belongs to the META-DX1 family of Ethernet MAC/PHY devices manufactured by Microchip Technology. It shares hardware compatibility and a common Software Development Kit (SDK) with related models such as the PM6110B-FEI and PM6104B-FEI, facilitating streamlined development across the product line.

Replacement Considerations

The PM6110B-FEI is a compatible substitute within the same family that includes integrated MACsec support. Designers must account for the absence of hardware encryption in the PM6108B-FEI if migrating from parts with built-in security features.
