Molex Launches Gemini Mezz Connectors for 224Gbps+ AI Applications
In July 2026, Molex introduced the Gemini Mezz Connector family, a compact, high-speed board-to-board solution designed to meet the extreme bandwidth demands of AI-driven data centers and high-performance computing .
The connector achieves 224Gbps+ PAM-4 data rates through fully shielded differential pair (DP) terminations that minimize crosstalk, EMI, and impedance variation—critical factors at next-generation speeds. The low-profile design has a 5.00mm stack height and supports up to 185 differential pairs in a grid-based layout .
Key Technical Specifications:
Data Rate: up to 224Gbps+ PAM-4
Pitch: 3.00mm
Stack Height: 5.00mm
Maximum DPs: Up to 185
Termination: BGA (Ball Grid Array)
Design: Self-mating, hermaphroditic
The hermaphroditic design simplifies the bill of materials (BOM) and inventory management by requiring only one component for both halves of a mated set. The fully shielded DP terminals significantly improve signal integrity in electrically noisy environments, accommodating tight loss budgets at high data transmission rates. The grid-based structure eases routing constraints and reduces PCB construction costs by minimizing the need for additional breakout layers .
Applications: High-performance computing, networking equipment, server racks, storage racks, and interposer applications .
