Product Brief

Marvell^®Alaska^®C 88X7121P

Dual 400G, Quad 200G, Octal 100G, 16 port 50G/25G/10G/1G Ethernet

Transceiver with 256-bit MACsec Encryption and Class C PTP Timestamping

Overview

The Marvell® Alaska® C 88X7121P is a fully integrated single

chip Ethernet transceiver that performs IEEE 802.1AE MACsec

encryption with 256-bit key and IEEE 1588v2 PTP

timestamping functionality for two ports of 400 GbE, four

ports of 200 GbE, 8 ports of 100 GbE, 16 ports of 50 GbE, 25

GbE, 10 GbE, and 1 GbE. The device supports full-duplex

transmission at all supported speeds, over a variety of media

including optics, passive direct attach cables, and copper

backplanes.

and termination capabilities for all FEC types deﬁned by IEEE

802.3cd, 802.3by, 802.3bj, 802.3ba, 802.3ap and the 25 Gigabit

Ethernet Consortium for 400 GbE, 200 GbE, 100 GbE, 50 GbE,

40 GbE, 25 GbE, and 10 GbE operation. The supported FEC

types include Clause-134 RS (544, 514), Clause-91 and Clause-

108 RS (528, 514) RS-FEC, and FC (2212, 2080) FEC.

The device supports Auto-Negotiation and coefﬁcient training

protocol required by IEEE 802.3 to support operation over KR

backplanes and CR passive copper cables. The device has a fully

symmetric architecture with Long Reach SerDes, FEC

generation and termination functionality, and Auto-Negotiation

and training capabilities on both host and line interfaces for

provide complete system design ﬂexibility.

The device also supports a variety of gearboxing modes to

translate between NRZ and PAM4 modes for 50 GbE and 100

GbE, with the necessary FEC termination and regeneration

required to translate between NRZ and PAM4 operation.

The PTP timestamping functionality in the device provides

timing accuracy that meets the requirements of Class C proﬁle,

enabling high precision timing recovery required for wireless

and carrier applications. The device provides recovered clock for

SyncE applications, with ﬂexible clock source selection.

The 88X7121P also supports 2:1 multiplexing functionality with

hitless switching capability on the host interface for

applications requiring redundancy.

The 88X7121P integrates Long Reach dual mode (PAM4 and

NRZ) SerDes, fully compliant to the IEEE electrical

speciﬁcations for transmission over passive direct attach cables

and copper backplanes. The device supports FEC generation
