Molex NearStack HD Connector System
Molex NearStack HD Connector System is a low-profile, high-density cable solution with 64Gbps PAM-4 speeds that meet PCIe Gen-6 standards. This connector system is designed for internal cable applications and supports Artificial Intelligence (AI) and machine learning applications. The NearStack HD connector system optimizes performance using robust and miniaturized connection solutions. This connector system enhances Signal Integrity (SI) with direct-to-contact termination and improves thermal performance using a small 34AWG twinax cable. The direct-to-contact termination system with twinax wires welded directly to the signal contact removes the paddle card from the assembly, which improves SI performance. Typical applications include data centers, storage devices, AI infrastructure, networking systems, and device control units.
