Samtec NovaRay® Cable Assembly Delivers PAM4 Signals in Dense Designs

Samtec, Inc., the service leader in the connector industry, has announced the availability of its NovaRay® cable assemblies. These assemblies 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 low (<30 dB, FEXT and NEXT) crosstalk 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 contact points contribute to its industry-leading 4.0 Tbps aggregate data rate. The NovaRay cable assemblies include two connectors with optional shielding and latching systems. While End 1 of the NovaRay cable assembly consists of a NovaRay connector, designers can select from a variety of End 2 options from the Samtec catalog depending on their application, including FQSFP, NovaRay I/O, ExaMAX® backplane, and upcoming NovaRay backplane.

NovaRay cable assemblies are available with 34 AWG EyeSpeed® ultra-low-skew Twinax cables (<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.
