Samtec has launched a high performance, low profile connector array for the latest COM-HPC standard with up to 400 pins and plans for a 1000 pin version

The AcceleRate HP High-Performance Arrays support 112 Gbps PAM4 data rates and is compatible with PCIe 5.0 and 100 GbEthernet. It uses an open-pin-field array which maximizes grounding and routing flexibility. System architects can route high-performance differential-pairs, single-ended signals and high-current voltage rails via the same interconnect.

The 2.2 / 2.4 / 2.2 mm row pitch eases routing of differential signals while crosstalk is minimised with the increased space and the ability to add more ground vias around the differential signals.

“Samtec’s new AcceleRate HP High-Performance Arrays set the standard for high-speed 112 Gbps PAM4 performance in a small form factor,” said Michael Boone, Product Manager, High-Speed Board-to-Board at Samtec, Inc. “Fast-growing applications such as AI accelerators, ASIC emulators and next-gen edge computing platforms leverage these unique benefits.”

The array has a 0.635 mm pitch with a low-profile 5 mm and up to 10 mm stack heights. Up to 400 total pins are available now with a roadmap to 1,000+ pins. BGA termination provides easy assembly and self-alignment
