Renesas showcases optical interconnects at virtual ECOC

Renesas Electronics will showcase its portfolio of optical communication products at this week's virtual European Conference on Optical Communication (ECOC) 2020:

Optical Communications for Datacom

PAM4-based solutions for datacom - featuring the industry’s first CMOS-based PAM4 CDR solution, the new HXT14450 CDR with integrated VCSEL driver and the HXR14450 CDR with integrated TIA are designed for 200G and 400G links and are also ideally suited for short range (SR) and Active Optical Cable operation for data centers. The series features significantly lower power and smaller size compared with traditional DSP solutions, as well as higher integration – including an integrated MCU – to further simplify system design. The series is certified for the -40°C to 85°C temperature range, making it ideal for optical communications links in 5G mid- and back-haul infrastructure. The standalone HXC44400 CDR is also available, and customers can combine it with Renesas DML drivers and TIAs to enable 200G long range links.

The lineup of high performance optical signal chain products also includes the HXT45411 family of EML drivers, HXT45430 Silicon-Photonics drivers, HXT44420 family of DML drivers and HXR45400 series TIAs for PAM4 deployments.

Optical Communications for Telecom

Renesas’ 64 GBaud GX76474 driver family and GX36420 series Coherent TIAs combine exceptional analog performance, low power, and high reliability with high bandwidth and configurability to support the telecom industry’s fastest growing segment – coherent optical communications. These new drivers and TIAs support all the key requirements to support the increased demands of longer range communication including:

  • Up to 400 Gbps of data speeds using industry-standard 64 GBaud modulation
  • Scalable solutions for 32G, 45G, and 64G, enabling customers to optimize either for speed or for power and cost, and to adjust key parameters via Serial Peripheral Interface (SPI)
  • The GX76474 and GX36420 series also cover all the optical modulator technologies currently on the market, including Lithium Niobate, Indium Phosphide, and Silicon Photonics, as well as both the industry-standard Integrated Coherent Receiver (ICR) and Transmitter Receiver Optical Sub-Assembly (TROSA) configurations.

“Over the last several months, data center, network, and telecom infrastructures have navigated significant increases in the demands and requirements placed on their systems, driven by increasing volumes of high-bandwidth data such as live and on-demand streamed content, the deployment of more AI-based systems, and a worldwide shift to the cloud as more consumers depend on connected systems for their work and daily life,” said Diwakar Vishakhadatta, Vice President of Optical Communication Products at Renesas. “
