Inphi launches first 32GBaud quad linear TIA and driver chipset for CFP2 digital coherent optics

Inphi Corp of Santa Clara, CA, USA (a provider of high-speed mixed-signal ICs for communications, computing and data-center markets) says that the IN3254TA, the first 32G quad linear transimpedance amplifier (TIA) with both analog and digital SPI interfaces, and the IN3226DZ, a second-generation single-chip quad-channel linear driver in bare die form, will be paired up as a chipset to address the network needs for 100/200G coherent systems in smaller form factors for metro and long-haul applications.

The IN3254TA and IN3226DZ are designed to be integrated together for higher-density and lower-cost applications, targeting new coherent optical sub-assembly (COSA) components. These COSA implementations will enable the newly proposed CFP2-DCO form factor as well as size- and cost-reduced ACO modules and higher-port-count line cards for 100/200G coherent transmission.

The optical transceiver market is expected to grow to $6.87bn by 2022. Social media, live streaming, cloud computing and big-data analytics are just a few of the trends that drive end-users' need for more bandwidth and higher speeds, notes Inphi. In the 100G environment, a large part of the growth is attributed to the CFP2 coherent modules expanding the addressable market for pluggable transceivers. This new range of transceivers is expected to enable the next generation of 100G and 200G networking infrastructure for the metro and inter-data-center markets where smaller size, lower cost and pluggable modules are the key factors.

Inphi’s family of dual and quad 32GBaud coherent TIAs have achieved multiple design wins with leading CFP2-ACO module vendors, says Dr Loi Nguyen, founder, senior VP, Optical Interconnect at Inphi. “With IN3254TA and IN3226DZ working together as a chipset we now enable more compact design solutions for the CFP2-DCO generation,” he adds.

“The small size, combined with high performance of Inphi’s TIA and driver are highly matched with our COSA devices, which in turn enable pluggable components such as CFP2-DCO,” comments Dr Senichi Suzuki, senior VP, Photonics Component Business Group, at Japan’s NTT Electronics Corp. “We are looking forward to industry-wide deployment and business growth of the coherent products.”

Inphi is showcasing its latest next-generation products in booth #3601 at the Optical Fiber Communications (OFC 2017) trade show in Los Angeles (21-23 March).
