Product details
Overview
PM6110B-FEI from Microchip Technology is a 1.2 Tbps Ethernet MAC/PHY IC supporting 1 GE to 400 GE rates, featuring 48 integrated 28G NRZ/56G PAM4 SerDes, line-speed MACsec encryption, and IEEE 1588v2 Class C/D timestamping for 5G transport and data center interconnect applications.
For engineers reviewing the PM6110B-FEI datasheet, PM6110B-FEI pinout, PM6110B-FEI application, or PM6110B-FEI equivalent, key selection criteria include PTP timestamp accuracy, FlexE support for bandwidth slicing, hitless 2:1 mux mode, gearboxing capability, and SerDes configuration flexibility across optical module interfaces.
Technical Context
The PM6110B-FEI implements dual-domain SerDes architecture with 24 host-side and 24 line-side lanes, enabling full-duplex 1.2 Tbps (PAM4) or 600 Gbps (NRZ) throughput. It integrates analog retiming, PCS-level retiming, forward/reverse gearboxing, and crosspoint switching for any-to-any SerDes connectivity.
It supports IEEE 1588v2 hardware timestamping with sub-500 ps accuracy for Class C/D compliance, SyncE, OTN retiming, and optional Interlaken interface for packet processor interfacing - all while delivering line-rate MACsec AES-256 encryption and FlexE 2.1 sublayer processing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Ethernet MAC/PHY applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PM6110A-FEI | Same SerDes count and MACsec capability, but lacks FlexE support and Interlaken interface | Suitable for non-DCI, non-slicing deployments where FlexE is not required | Select when FlexE and Interlaken are unnecessary to reduce cost and firmware complexity |
| PM6108B-FEI | Identical feature set including FlexE, MACsec, and PTP Class C/D, but with reduced SerDes configuration options | Targeted at lower-density line cards or cost-sensitive DCI edge platforms | Choose for applications needing full META-DX1 functionality at lower channel count or simplified thermal profile |
Compared with PM6110B-FEI, PM6110A-FEI omits FlexE and Interlaken - limiting DCI slicing and packet processor integration - while PM6108B-FEI retains full feature parity but offers fewer SerDes configuration modes, making it better suited for constrained board space or thermal budgets.

FAQ
What Ethernet rates does the PM6110B-FEI support?
The PM6110B-FEI supports client Ethernet rates from 1 GE to 400 GE across its 48 SerDes lanes. It achieves this through flexible NRZ (28G) and PAM4 (56G) signaling, with gearboxing and muxponding enabling rate adaptation between dissimilar interfaces - for example, aggregating eight 50G clients into a single 400G line interface. This makes PM6110B-FEI suitable for both legacy upgrades and greenfield 400G deployments.
Does the PM6110B-FEI include hardware MACsec encryption?
Yes, the PM6110B-FEI integrates a line-rate MACsec engine compliant with IEEE 802.1AE-2018, supporting AES-256-GCM encryption and decryption at full SerDes bandwidth. The PM6110B-FEI performs frame-level encryption without CPU involvement or packet buffering delays, enabling end-to-end security for WAN-bound traffic in routers, switches, and encryption appliances.
What is the PTP timestamp accuracy of the PM6110B-FEI?
The PM6110B-FEI delivers hardware-based IEEE 1588v2 timestamping with sub-500 ps resolution and stability, meeting Class C and Class D requirements for telecom and 5G fronthaul applications. Timestamp capture occurs at physical layer ingress/egress points, eliminating software stack variability - a capability confirmed in Microchip's DS00003280A datasheet and validated in carrier lab testing of the PM6110B-FEI.
Can the PM6110B-FEI operate in hitless 2:1 mux mode?
Yes, the PM6110B-FEI supports hardware-assisted hitless 2:1 multiplexing, allowing seamless traffic failover between working and protect paths with zero packet loss. This function is implemented entirely within the PM6110B-FEI's SerDes and crosspoint logic, requiring no external arbitration or software intervention - a key requirement for ITU-T G.8032 Ethernet ring protection and carrier-grade redundancy schemes.
Is FlexE support included in the PM6110B-FEI?
Yes, the PM6110B-FEI implements full FlexE 2.1 functionality, including calendar-based multiplexing, sub-rate client mapping (e.g., 10/25/50G into 400G), and overhead processing. FlexE operation is hardware-accelerated and independent of host software, enabling bandwidth slicing for DCI applications without adding latency or CPU load - a capability explicitly documented for the PM6110B-FEI in Microchip's META-DX1 family datasheet.
