Product Brief

Marvell^®Alaska^®C 88X5123

Dual 100G/40G, Quad 50G, Octal 25G/10G Ethernet Transceiver

Overview

The Marvell® Alaska® C 88X5123 is a fully integrated device that

performs all physical layer functions required to drive 100G,

50G, 40G, 25G, 10G, 5G, 2.5G and 1G Ethernet over a variety of

media including; optics, backplanes and passive copper cables.

Manufactured with 28 nanometer (nm) lithography, in a small

17mmx17mm 256 pin FCBGA package footprint, the Alaska C

88X5123 enables low-power dissipation, high density 100GbE,

50GbE, and 25GbE line card designs.

The device supports 40GBase-R2 to 40GBase-R4 gearboxing

functionality to enable high-density 40GbE applications on

switch ASICs with native 25G I/Os. For applications not

requiring the FEC functionality, the device also supports a low

latency retimer mode where the functionalities associated with

the PCS and FEC are bypassed. In this mode, the 88X5123

supports a hole free operation from 1.25Gbps to 28.05Gbps to

support a wide variety of standards and rates. The device

includes internal PRBS generators and loopbacks to assist with

test and debug. In addition, nondestructive eye monitoring is

supported on all high speed I/Os.

The line interface and host interfaces of the 88X5123 are fully

compliant to the IEEE 802.3bj and IEEE 802.3by standards

100Gb and 25Gb Ethernet operation. The device supports all

the FEC conﬁgurations speciﬁed by IEEE 802.3bj, and 802.3by

standards as well as the 25/50G Ethernet consortium. The

device also supports auto-negotiation and coefﬁcient training

protocol required by the IEEE 802.3 and 25/50G consortium

speciﬁcations for twinaxial cable and backplane applications.
