Microchip announces Terabit-Scale Ethernet PHY with MACsec

Microchip Technology introduced its META-DX1 family of Ethernet Physical-Layer (PHY) devices that integrates, onto a single chip, Ethernet ports from 1 Gigabit Ethernet (GbE) to 400 GbE, flexible Ethernet (FlexE), Media Access Control Security (MACsec) link encryption and nanosecond timestamping accuracy at terabit capacity.

The META-DX1, which was developed by Microchip's Microsemi division, enables line cards to quadruple in capacity – from 3.6 terabits per second (Tbps) to 14.4 Tbps with 36 ports of 400 GbE or 144 ports of 100 GbE – while supporting key features needed by service providers.


The META-DX1 family uniquely combines MACsec and FlexE into one solution. The META-DX1 MACsec engine secures traffic leaving the data center or enterprise premises, and FlexE enables both cloud and telecom service providers to meet capacity requirements while reducing fiber plant capital expenditures by optimally configuring links beyond today’s fixed-rate Ethernet so they can use low-cost, high-volume optics.

High-performance timestamping enables nanosecond-level accuracy on every port. This will support timing requirements of 5G mobile base stations.



The META-DX1 also brings a flexible crosspoint switching capability that makes it easier for OEMs to navigate the market transition from 25 Gbps NRZ and 56 Gbps PAM-based architectures by enabling them to support a single design or SKU for both 100 GbE (QSFP28) and 400 GbE (QSFP-DD) optics.

“The META-DX1 family was purpose-built to unify into a single hardware and software offering the broad range of capabilities service providers need in their network buildouts that connect enterprise and data center services to the cloud and emerging 5G applications,” said Babak Samimi, vice president for Microchip’s Communications business unit.  “By delivering the highest-density Ethernet ports coupled with MACsec, FlexE and the nanosecond packet timing performance needed for 5G, we’ve introduced an innovative Ethernet connectivity platform for telecom and cloud service provider routers and switches, as well as optical transport equipment.”

Initial META-DX1 family members will sample during Q3 2019.

Microsemi and Acacia collaborate on Flexible Rate Optical at up to 600G

Microsemi and Acacia Communications announced interoperability between Microchip’s DIGI-G5 Optical Transport Network (OTN) processor and Acacia’s AC1200 Coherent Module.

Microsemi's DIGI-G5 OTN processor supports FlexE and OTUCn protocols, enabling new terabit scale line cards with flexible rate optical interfaces for packet optical transport platforms. Acacia's AC1200 modules support for metro and data center interconnect networks. Specifically, while the DIGI-G5 processes client traffic into OTN, the 1.2T AC1200—powered by Acacia’s Pico digital signal processor (DSP) ASIC—on the line card will enable the OTN connections over two 600G tunable DWDM wavelengths with flexible transmission three-dimensional (3D) shaping features. These features, which include fractional quadrature amplitude modulation (QAM) and adaptive baud rate optimize transmission reach and capacity, approaching theoretical limits on a wide range of network configurations, in a power efficient manner.

The companies said their collaboration enables the first flexible rate system architectures with an established ecosystem to support the market’s transition to 200G, 400G, 600G and flexible rate OTN networks built with new Flexible Ethernet (FlexE) and OTUCn protocols. FlexE was designed to provide up to 30 percent greater bandwidth efficiency compared to traditional Ethernet link aggregation (LAG) with fewer limitations. Combining it with OTUCn and tunable fractional dense wavelength division multiplexing (DWDM) transmission brings service providers the potential to improve their OTN network capacity by up to 70 percent.

Microchip to Acquire Micrel for $744 Million

Microchip Technology, which supplies microcontroller, mixed-signal, analog and Flash-IP solutions, agreed to acquire Micrel for $14.00 per share, representing a total equity value of about $839 million, and a total enterprise value of about $744 million.

Micrel, which is based in San Jose, California, is a leading manufacturer of IC solutions for the worldwide high-performance analog and high-speed mixed signal, LAN and timing and communications solutions markets. Its products include high performance analog, power, advanced mixed-signal and radio frequency semiconductors; high speed communication, clock management, and LAN solutions including Ethernet switch and physical layer transceiver integrated circuits. These products address a wide range of rapidly growing end markets including cellular handsets, portable and enterprise computing, enterprise and home networking, wide area and metropolitan area networks and industrial equipment. Micrel was founded in 1978 and has been profitable in 33 of its 34 years of its existence. The Company has consistently generated positive cash flows since going public in 1994.

"We are pleased to have Micrel become part of the Microchip team. Micrel's portfolio of Linear and Power Management products, LAN solutions and Timing and Communications products, as well as their strong position in the Industrial, Automotive and Communications markets, complement many of Microchip's initiatives in these areas.  We believe that combining Micrel's business with Microchip's business will enable significant synergies and cross selling opportunities," said Steve Sanghi, President and CEO of Microchip Technology.  "Ray Zinn founded Micrel and has led the company for the last 37 years.  I want to thank Ray for his vision in guiding Micrel from a start-up to almost a quarter billion dollars in annual sales," added Mr. Sanghi.

"We are excited to join Microchip Technology, a premier company in the semiconductor industry. Microchip has demonstrated consistent profitability, technology leadership and growth in its core businesses.  We believe that this acquisition provides the best vehicle for us to realize significant value for Micrel's shareholders and is a fantastic outcome for our employees and customers, as well as the opportunity to scale up to the much stronger sales and manufacturing platforms of Microchip," said Ray Zinn, President and CEO of Micrel.
