Marvell Technology Group, Ltd. Adds to its Alaska C Ethernet Transceiver Family


(Santa Clara, CA) The electronic circuit, physical layer, is abbreviated PHY.  For the most part, this type of electronic circuit is implemented as a chip.  The purpose is to implement physical layer functions of the O.S.I. Model.  This is done by connecting a link layer device, to a physical medium.  For example, a M.A.C. or medium access control, to, an optical fiber or copper cable.  When it comes to a PHY device; a physical coding sublayer (P.C.S.), and, physical medium dependent (P.M.D.) are required.  At the same time, and also operating a physical layer of the O.S.I. Network Model is, the Ethernet PHY.  Recently, Marvell Technology Group, Ltd. announced that, it has arrived at the milestone industry’s first.  Specifically, the aforementioned business revealed that, it has added to its Alaska C Ethernet transceiver family.  The latest edition is officially named, Marvell’s Alaska C 88X9121P.  The latter, is the industry’s first dual 400 GbE physical layer (PHY) transceiver.
            The dual 400 Gigabit Ethernet (GbE) PHY transceiver function, of Marvell’s Alaska C 88X9121P, also comes with the following.  The 88X9121P comes with 100 G serial input/output (I/O), and, a M.A.C. Security feature.  M.A.C. Security, also MACsec, is an 802.1AE I.E.E.E. security technology solution.  The purpose is to provide secure communications, for all traffic on Ethernet links.  However and returning to, Ethernet PHY, the aforementioned is also called Ethernet physical transceiver.  The Ethernet physical layer portion is usually based on the standards; 1000BASE-T, 100BASE-TX and 10BASE-T.  In a more technical manner, an Ethernet PHY is a chip.  This chip successfully implements the hardware, send and receive functions of Ethernet frames.  The purpose is to interface between the analog domain of the Ethernet’s line modulation, and, the digital domain of link layer packet signaling.  A network interface card (N.I.C.) can be one chip, or, it can be several independent chips.  Irregardless of which, an N.I.C. can contain a PHY, M.A.C or other types of functions.
            Returning to, Marvell’s Alaska C 88X9121P, the aforementioned technology solution is an integrated circuit transceiver (I.C.) or chip.  Additionally, it has a serializer/deserializer (SerDes) feature.  This feature converts parallel data into serial data, and, vice versa.  The previously said; is perfectly suited for high density implementations in the data center, and, the internet cloud.  As previously said, the 88X9121P is the technology industry’s first, dual 400 GbE physical layer (PHY) transceiver.  Additionally, it comes with 100 GbE serial electrical I/O capabilities.  The idea is to lead the next generation, of secured high density optical infrastructure.  In order to accomplish this effort, three features help to define Marvell’s Alaska C 88X9121P.  The first feature that defines, is the 100 G serial inputs/outputs enable the doubling of faceplate bandwidth.  The latter, occurs at the data center network.  Additionally; it reduces the total power consumption, and, cost per bit.  The second feature that defines, is the 256 bit M.A.C Security encryption.  The latter, ensures a heightened point to point security.  Additionally; it provides a compliant Class C precision time protocol (P.T.P.), time stamping that enables synchronization and a 112 G P.A.M 4 serializer/deserializer.  The serializer/deserializer is meant for use on high density 400 GbE, and, 100 GbE deployments.  The third feature that defines is; the 88X9121P is completely compliant with I.E.E.E. standards for 400 GbE, 100 GbE and 50 GbE.  The latter; actually exceeds the electrical specifications that are needed, to be able to, interface with Q.S.F.P.-D.D. and O.S.F.P. optical modules.  Bob Wheeler is a Principal Analyst for Networking at The Linley Group.  Through a press statement, Mr. Wheeler said the following.  “We see 100Gbps serial I/O as a foundational speed and expect it will enable 400GbE port shipments to reach 6.5 million by 2023.  Marvell’s new PHY is a milestone in kickstarting the ramp of 100Gbps-serial-electrical optics and will help accelerate the deployment of 400GbE in cloud data centers.”
            To end, Marvell Technology Group, Ltd. (NASDAQ:  MRVL) did release press statements.  Faraj Aalaei is the Executive Vice President of the Networking Business Group at Marvell Technology Group, Ltd.  Through a press statement, Mr. Aalaei said the following.  “We see the introduction of our feature-rich 100G serial I/O based, dual 400GbE PHYs playing a major role in the next evolutionary phase of the global data center and cloud sectors.  The transition to 100G serial signaling is critical for high-density optical interconnects required for next-generation switching solutions. Our newest PHY transceivers will help drive the industry transition to 100G serial I/O-based optics as data centers and cloud providers look to bring greater computing bandwidth and efficiency to their customers.”  Sandeep Bharathi is the Senior Vice President of Central Engineering at Marvell Technology Group, Ltd.  Through a press statement, Mr. Bharathi said the following.  “Marvell has a rich history of innovation in SerDes technology that is further strengthened by our SoC design and Ethernet expertise.  Our newest PHY transceiver device extends Marvell’s SerDes technology leadership by integrating our state-of-the-art 112G PAM4 SerDes solution in advanced FinFET process into the industry’s first dual 400GbE MACsec PHY with 100GbE serial I/Os.”  As previously stated, Marvell Technology Group, Ltd. recently announced that, it has arrived at the milestone industry’s first.  Specifically, the aforementioned business revealed that, it has added to its Alaska C Ethernet transceiver family.  The latest edition is officially named, Marvell’s Alaska C 88X9121P.  The latter, is the industry’s first dual 400 GbE physical layer (PHY) transceiver.  Lastly; the 88X9121P comes with 100 G serial input/output (I/O), and, a M.A.C. Security feature.
