LineSpeed MSH221 Octal Retimer with RS-FEC and MSH321 Multi-Link
Gearbox for 100G Module and Line Card Solution Support Latest IEEE
802.3bj RS-FEC and OIF MLG2.0 Capabilities

SANTA CLARA, Calif.–(BUSINESS WIRE)–Sep. 22, 2015–
MoSys

(NASDAQ: MOSY), a leader in semiconductor solutions that enable fast,
intelligent data access for network and communications systems, today
announced two new members of its LineSpeed™
100G PHY
family, the 100G Multi-Link Gearbox (MLG) and the Octal
100G Retimer with RS-FEC (Reed Solomon Forward Error Correction). The
MSH321 MLG device enables high-density, independent 10GE and 40GE
interfaces to be multiplexed into a single 100GE interface. The MSH221
Retimer with 802.3bj 100G RS-FEC enables 4x25G (100G) interfaces to be
compliant to the latest 100G IEEE standards and Multi-Source Agreements
(MSA) including SR4, CWDM4, PSM4 and others that are specified with FEC.

The MoSys® LineSpeed 100G Octal Retimer with integrated RS-FEC supports
up to 4 full duplex lanes (8 channels) with independent rates up to 28
Gbps for high data rate line card applications up to terabits per second
(Tbps). This flexible, multi-protocol SerDes device includes an option
for the Clause 91 RS-FEC specified in 802.3bj for 4x25G NRZ interfaces.
When the RS-FEC is turned off, the MSH221 device functions as a standard
multi-rate and multi-protocol retimer capable of passing data whether
encoded or non-encoded. Each lane is independent and supports a broad
range of frequencies compatible with 10G, 25G, 40G and 100G Ethernet and
OTN standards. With the 100G 802.3bj RS-FEC encode, decode and
correction functions enabled, the device will encode data in one
direction and decode and correct data (if needed) in the other
direction. The IEEE 802.3bj RS-FEC standard enables additional signal
integrity and/or distance capability over copper or optical
interconnects and has been specified in multiple standards and MSAs.

The LineSpeed Multi-Link Gearbox supports both OIF MLG-1.0 and MLG-2.0
standards that aggregate a combination of 10GE and 40GE links, up to
100G total bandwidth, and converts that to a single 100GE (4x25G) link.
The difference between the MLG and a standard gearbox based on IEEE
802.3ba is that rather than requiring all 10 lanes to be bonded as
10x10G with zero ppm offset, MLG allows independent 10GE or 40GE lanes,
separated by up to +/- 100ppm to be multiplexed into a single 100GE
pipe. The MLG device performs all alignment marker insertion and
awareness, idle insertion and deletion, and data alignment required by
the OIF MLG standards. As physical interfaces on switching and packet
processing ICs move to 25G PHY interfaces for performance and board
density, the MLG function allows large-scale systems built with these
devices to support higher port counts of legacy 10GE and 40GE interfaces.

"We are excited to announce the availability of the retimer and gearbox
devices leveraging the 100G RS-FEC and MLG technology," stated John
Monson
, VP of marketing and sales for MoSys. "These devices will
help customers to build equipment that is compliant to the latest 100G
industry standards and capable of higher 10G and 40G port densities."

"We see the 100G network and data center infrastructure expanding,
driven by the broad availability of the latest silicon and optical
module technology," said Loring
Wirbel
, senior analyst with The Linley Group. "Devices such as
MoSys’ latest LineSpeed PHYs, which are on the forefront of supporting
OIF MLG 1.0 and 2.0 and which support the latest 100G standards to
enable higher 10, 40 and 100G port density, low cost optical modules,
and broad interoperability, will be essential to that growth
opportunity."

The MoSys LineSpeed 100G Octal Retimer and Multi-Link Gearbox products
will be demonstrated at ECOC 2015 in Valencia, Spain. Contact MoSys or
