Section 2: Selection, Compatibility, and Alternative Solutions Reference and Recommendations
In practical projects, engineers usually need to consider interface type, cable length, impedance control, and device structural space when selecting PCIe high-speed cables. For PCIe x8 extension components such as 8KH2-0723-0150, the following selection suggestions can be referred to:
Key selection parameters
• PCIe channel count (x4/x8, etc.)
Cable Length (150mm, 250mm, 500mm, etc.)
Differential impedance requirement (usually 85Ω)
Cable structure (Twinax or high-speed shielded structure)
Plug and card edge interface match
Compatibility and substitution approaches
On the premise of maintaining the PCIe x8 interface structure, 98Pin definition, 85Ω impedance, and dual-axis structure, compatible cable components can be developed.
For servers or industrial control equipment, different length versions can be selected according to the installation space, such as 150mm, 250mm, or 500mm.
The domestic alternative can achieve cost control and optimization of supply cycle by optimizing cable materials and production processes, based on meeting high-speed signal integrity and shielding structure requirements.
