Inphi Delivers 2nd Generation CMOS PHY/SerDes Gearbox With Tri-Rate Support for 10G, 40G and 100G Ethernet and OTN Line Cards

SANTA CLARA, CA -- (Marketwire) -- Mar 18, 2013 -- Inphi Corporation (NYSE: IPHI), a leading provider of high-speed, mixed signal semiconductor solutions for the communications and computing markets, today introduced its second generation 100G CMOS PHY/SerDes Gearbox (GB) IC for data center, enterprise and service provider line cards. Delivering the industry's most aggressive power and performance metrics, the new GB ICs with Inphi's Tri-Rate™ foundation enables seamless support of 10G, 40G and 100G Ethernet and OTN on a single line card. This second generation Tri-Rate PHY/SerDes is available in two variants:

  • IN112510-LD 100G GB for line cards, used alongside CFP2, CFP4 and QSFP28 modules
  • IN111010-LD 10x10G Retimer for line cards, used alongside SFP+, QSFP+ and CXP modules

Built on top of the foundation of Inphi's first generation PHY/SerDes GB the IN112510-LC, the second generation Inphi GB ICs are built to support Tri-Rate line cards while exceeding critical performance parameters in the IEEE 802.3ba, SFF-8431, OIF-28G-VSR and ITU specifications.

Inphi's 100G CMOS PHY/SerDes GB is based on the unique and groundbreaking iPHY™ architecture which is purpose built for client side networking interfaces that push the envelope on power, performance, integration, latency and cost. Unlike other GB and FPGA offerings that attempt to cover too many data rates in unrelated applications, Inphi's GB is purpose-built for supply power and performance sensitive 10G, 40G and 100G optical line cards for enterprise and data center networks. Consuming as low as 2.3-W, latency < 15-ns and Rj < 180fs rms, Inphi's new IN112510-LD is the lowest power, highest performing CMOS PHY/SerDes GB IC in the industry.

Inphi Tri-Rate PHY/SerDes GB Now Sampling
The second generation iPHY PHY/SerDes is a single-chip, low-power PHY for 10:4 GB and 10:10 retimer applications. These cover 10G, 40G, 100G Ethernet and OTN high-density line cards with 10G and 25-28 Gbps electrical interfaces. Other technical features include:

  • IEEE 802.3ba 100GBASE-LR4/ER4 to CAUI Gearbox
  • 100GASE-SR10 Retimer IEEE 802.3ae
  • 10GBASE-SR/LR/ER Retimer (10 lanes)
  • IEEE 802.3ba 40GBASE-SR4/LR4 Retimer (2 lanes)
  • Tri-Rate Support Allows Seamless Support of 10/40G/100G on a Single Line Card
  • High Resolution Eye-scan (iSCAN™) Tool
  • Link Monitor Kit - Protocol and Lane Snooping Capabilities
  • Several Integrated Test Features for Lab, System and Production Test
  • Adaptive Receive Equalization on 10/28G Interface
  • Programmable Transmit Equalization

"Inphi established itself as the leader in the 100G connectivity arena with the world's first CMOS GB in 2011 and we are now pleased to have moved to our second generation GB offerings targeted for datacenter and enterprise networks. Targeting our GB into this market segment with our Tri-Rate PHY offering, will allow Inphi to tap into the hyper-growth of 10G and 40G interfaces while 100G interfaces gradually ramp up in volume," said Siddharth Sheth, vice president of marketing for Inphi's high-speed connectivity products.

"The data center switch market is witnessing a lot of port count growth for 10G and 40G," said Seamus Crehan, president and founder of Crehan Research. "By targeting its Tri-Rate PHY/SerDes technology for the 10G, 40G and 100G market segments, Inphi should benefit from this growth as data center operators are able to seamlessly transition across these port speeds with this Tri-Rate architecture."

According to Jag Bolaria, senior analyst at The Linley Group, "Inphi was the first to sample and first to production with its first generation 100G CMOS PHY/SerDes GB. By building the second generation Tri-Rate PHY/SerDes GB on its successful initial offering, Inphi offers a low risk and proven 100G PHY/SerDes GB solution for the high volume data center and enterprise switch applications."
