Samtec UDx6 AcceleRate® mP 0.635 mm Signal/Power Arrays

Introduction

Samtec UDx6 AcceleRate® mP arrays are high-density board-to-board connectors designed for demanding high-speed digital systems. With a fine 0.635 mm pitch and integrated signal and power contacts, these connectors help designers build compact interconnects capable of supporting modern compute, networking, storage, and accelerator platforms.

Part Description

The Samtec UDx6 series is a connector family that combines high-speed signal transmission with power delivery in a compact array format. It supports data rates up to 64 Gbps PAM4 and 32 Gbps NRZ, making it suitable for advanced serial links and high-bandwidth system architectures.

A key feature of the UDx6 family is its rotated power blade arrangement. This design supports effective power distribution while preserving a dense signal-contact field. Its open-pin-field structure gives engineers flexibility when assigning differential pairs, grounds, power connections, and reserved contacts across an interconnect.

The low-profile stack-height options make the connector useful where board spacing is limited, including densely packed embedded systems and modular electronics. The UDx6 platform is also positioned for PCIe® 6.0 and CXL® 3.2-capable designs, allowing it to support emerging high-performance compute and memory-expansion interconnect requirements.

Applications

Potential applications for Samtec UDx6 connectors include:

• High-speed board-to-board interconnects
• PCIe 6.0 expansion architectures
• CXL 3.2 memory and accelerator connections
• Server and data-center platforms
• Network switches and routers
• Storage controllers and NVMe systems
• FPGA and ASIC carrier boards
• AI and machine-learning accelerator modules
• Telecom line cards
• Embedded compute modules
• High-performance test and measurement equipment
• Modular instrumentation systems
