Samtec NovaRay cable assembly delivers PAM4 signals in dense designs

Samtec 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 PCIe6.0/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 catalogue 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 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.
