MoSys Announces LineSpeed Flex Family of 100G and 25G PHYs

LineSpeed Flex MSH320 Gearbox with RS-FEC, MSH322 100G Multi-Link Gearbox, and MSH225 10-Lane Full-Duplex 25G Retimer provide feature rich, pin-compatible solutions to support the latest Ethernet and optical MSA standards

MoSys today introduced its new LineSpeed™ Flex family of 100G PHYs. The PHY devices are designed to support the latest industry standards, including the Optical Internetworking Forum (OIF) Multi-Link Gearbox (MLG) 1.0 and 2.0 specifications, IEEE 802.3 clause 91, RS-FEC, and 25G Ethernet. The LineSpeed Flex family is pin and software compatible and includes gearbox, MLG, and high density retimer devices designed to enable existing and next generation Ethernet and OTN line card applications to support the latest high-density electrical and optical interfaces.

The LineSpeed Flex family of 100G PHYs is designed to support a number of key line card platform requirements.

1. 100G Gearbox with RS-FEC (MSH320): For adapting 10×10 to 4×25 from 100G optical standards like LR4 or ER4 to a host ASIC, MAC/Framer, NPU or FPGA with 10x10G interfaces. The MSH320 includes an integrated Clause 91 RS-FEC option to enable systems to also support new electrical and optical standards such as SR4, CWDM4 and PSM4. The device also includes a 10x10G retimer to allow seamless support of 10 and 40G interfaces.
2. 10 Lane Full-Duplex Retimer (MSH225): For high density retiming applications where the line rates may be up to 28G per lane and connect to host ASIC, framer/OTN, NPU or FPGA equipped with 25G interfaces. Each one of the 20 total independent lanes can be configured to support 10, 25, 40 or 100G standards. The MSH225 integrates optional 100G RS-FEC capability and includes a unique redundant link mode feature to support redundancy, scaling or monitoring features.

3. 100G Multi-Link Gearbox for Line Cards (MSH322): For support of high density, independent 10GE and 40GE interfaces multiplexed into a 100GE (4x25G) host interface, the MSH322 multi-link gearbox supports the OIF MLG 1.0 and 2.0 standard. The device enables line cards with high-density switches based on 25G interfaces to support two times the density of 10 and 40G ports. MoSys has also optimized features and pinouts to support the multi-link gearbox function in module applications with the previously announced LineSpeed MSH321 device.

“We are pleased to announce these latest additions to the LineSpeed family of PHY ICs,” stated John Monson, VP of marketing and sales for MoSys. “The LineSpeed Flex devices include the latest RS-FEC and MLG options in a common configuration, pinout and software platform, enabling customers to support a broad range of architectures and host device interfaces.”

“New 100G and emerging 25G standards are being developed to establish a robust and low cost 100G electrical and optical ecosystem and 25G is likely to emerge as the next single lane rate of choice,” said Simon Stanley, analyst at large at Heavy Reading. “MoSys’ LineSpeed family of retimers is a good example of the type of flexible PHY products that will be required to ensure compatibility between systems and support the newest electrical and optical standards.”

The LineSpeed Flex devices are sampling now. For additional information about LineSpeed Flex 100G PHY products including availability and pricing, contact a local MoSys sales representative at http://www.mosys.com/contact.php.
