PCIe 3.0 x1 Tx to Rx Cross Over Jumper Cable, Male to Female

The PCIe 3.0 x1 Tx to Rx Cross Over Jumper Cable, Male to Female, is a specialized passive interconnect solution designed for establishing standard-compliant PCIe connections between different port types in test, development, and diagnostic applications. This cable implements the correct PCIe communication protocol by crossing the Transmit (Tx) lanes from one end to the Receive (Rx) lanes on the opposite end, enabling proper communication between PCIe devices. Engineered for PCIe 3.0 systems operating at 8.0 GT/s per lane, this male-to-female crossover jumper provides approximately 985 MB/s bandwidth for x1 configurations. The combination of male and female connectors offers flexible interconnection options between various PCIe devices and test equipment. Constructed with precision impedance-matched wiring and comprehensive EMI shielding, this cable is ideal for benchtop testing, prototyping, and creating direct links between PCIe-based systems with different connector requirements.

Compatibility Notes

• Standard Compliance: This cable follows PCI-SIG standard pinout and can enable functional communication between compatible PCIe devices with different connector types
• Length Considerations: Passive PCIe 3.0 cables are subject to signal integrity constraints. For reliable operation at 8.0 GT/s, keep cable length under 0.5m
• Power Limitations: PCIe x1 slots provide limited power (up to 10W). Ensure connected devices do not exceed this limit to avoid instability
• Connection Compatibility: Verify that connected devices support the same PCIe generation and can establish a link through this crossover configuration
• Mechanical Stress Management: Avoid excessive bending or torsion near connector interfaces to maintain impedance continuity and prevent mechanical damage
• Hot-Plug Considerations: While PCIe standards support hot-plugging, functionality depends on the connected devices and system firmware. Consult device documentation before hot-plugging
• Signal Integrity Verification: For critical applications, validate signal quality using appropriate test equipment, especially when using cables at maximum recommended length
