Cable GEN Z 4C to PCI-E 5.0 X16 Lenght 250mm

Cable: Gen-Z 4C to PCI-Express 5.0 x16 High-Speed Interconnect

This high-performance cable assembly provides a direct, low-latency connection between a Gen-Z 4C interface and a PCI-Express 5.0 x16 host or adapter. It is designed for next-generation servers, storage, and accelerator platforms that require extremely high bandwidth and signal integrity across short to mid-length chassis or rack-level links.

Electrical / Protocol Characteristics

• Interface A: Gen-Z 4C (4-lane, high-speed differential pairs)

  • Optimized for point-to-point, memory-semantic and fabric-style links

  • Supports multi-gigatransfer signaling with embedded clock and advanced equalization

• Interface B: PCI-Express 5.0 x16

  • Aggregate raw bandwidth up to 32 GT/s per lane, 16 lanes (up to 512 GT/s raw)

  • Backwards-compatible at the PCIe level with Gen4/Gen3 link training (platform-dependent)

• Signaling:

  • Differential high-speed pairs for data lanes

  • Low-skew reference clock / sideband control lines as required by platform design

  • Controlled differential impedance nominally 85 Ω (±10%) for high-speed pairs

• Performance Focus:

  • Optimized to maintain PCIe 5.0 link quality (eye opening, jitter margin, and insertion loss budget) between Gen-Z device-side PHY and PCIe x16 host connector

  • Low crosstalk construction with pair-to-pair and intra-pair skew tightly controlled
