Samtec NovaRay® Cable Assembly Delivers PAM4 Signals in Dense Designs

Innovative, fully shielded differential pair design enables extremely low crosstalk and tight impedance control.

[New Albany, IN]– Samtec, Inc., the service leader in the connector industry, has announced availability of its NovaRay® cable assemblies that combine extreme density and performance by using 40% less space than traditional arrays to support 112 Gbps PAM4 per channel. Applications include datacom, AI/ML, HPC, computer and semiconductor, medical, test and measurement, military/aerospace, and mobile networks.

Samtec’s NovaRay cable assemblies enable extremely low (<30 dB, FEXT and NEXT) crosstalk out to 40 GHz. Operating across -40 to +125˚C, the NovaRay cable assemblies (part number NVAC) are PCIe®6.0/CXL® 3.1 capable.

The innovative design of the Samtec NovaRay connector combines extreme performance with extreme density, which is critical as speeds increase and system sizes decrease. The fully shielded differential pair design and two reliable points of contact contribute to its industry-leading 4.0 Tbps aggregate data rate. The NovaRay cable assemblies include two connectors and are available with optional shielding and latching systems. While End 1 of the NovaRay cable assembly includes a NovaRay connector, designers can select from a variety of End 2 options from the Samtec catalog depending on their application, including FQSFPNovaRay I/OExaMAX® backplane, and upcoming NovaRay backplane.

NovaRay cable assemblies are available with 34 AWG EyeSpeed® ultra-low-skew twinax cable (<3.5 ps/meter). Options include 34 AWG/100 Ω, 34 AWG/92 Ω, and 34 AWG ThinaxTM/92 Ω ultra-performance cable (with a 40% smaller cross-sectional area). The 92 Ω solutions address both 85 Ω and 100 Ω applications.

Samtec’s NovaRay cable assemblies are in stock and available now, directly from Samtec or through authorized distributors. Samtec SI experts can be reached directly for design assistance at

Easily Connect to AWS Cloud with ExpressLink Over Wi-Fi
Sponsored by Mouser Electronics and AWS and u-blox
In this episode of Chalk Talk, Amelia Dalton, Lucio Di Jasio from AWS and Magnus Johansson from u-blox explore common pitfalls of designing an IoT device from scratch, the benefits that AWS IoT ExpressLink brings to IoT device design, and how the the NORA-W2 AWS IoT ExpressLink multiradio modules can make retrofitting an already existing design into a smart AWS connected device easier than ever before.
