Features
● Supports dual PCIe 5.0 MCIO 8i input connections
● Provides one PCIe x16 mechanical and electrical slot output
● Supports PCIe Gen5 x8 mode using a single MCIO cable
● Supports PCIe Gen5 x16 mode using dual MCIO inputs
● x8 mode uses input near the power connector
● x16 mode requires both MCIO inputs connected
● x16 mode requires both inputs from the same CPU host port
● Lane ordering must be 0–7 → 8–15
● Reversed lane mapping (8–15 → 0–7) is not supported
● Built with high-quality PCIe Gen5 SMT slot
● Uses 85Ω ultra low-loss PCB for high-speed signal integrity
● Integrated GPU power connector for external 12V supply
● Built-in 12V → 3.3V buck voltage regulator (6A design)
● Designed for PCIe Gen5 GPU and accelerator expansion applications
