U.2 (SFF-8639) INTERPOSER
SerialTek’s PCIe Gen4 U.2 and U.3 Interposers with SI-Fi technology are specially designed test adapters that are physically placed in between the U.2/U.3 port and an U.2/U.3 target to intercept and relay a copy of the high-speed signaling and discrete data lines to the Kodiak PCIe Analysis system in real-time.
SerialTek’s U.2, U.3, single-port (1×4), and dual-port (2×2) capability is combined into one interposer unit, providing significant cost savings in enterprise environments where all form factors are required. SerialTek’s U.2 and U.3 interposers support standard and extended length storage bays, and all relevant sidebands, including SMBus (e.g., NVMe-MI) from the host or from external / third-party injection or generation tools.
Key Features
- Compliant with PCI Express 1.x, 2.x and 3.0 specifications
- Accurate capture of PCIe data traffic at line rates including 8.0 GT/s (Gen3), 5.0 GT/s (Gen2), and 2.5 GT/s (Gen1)
- Standard- and Extended-length to accommodate all drive bays
- Single device supports both singleport and dualport capture (requires 2nd analyzer)
- Next-gen Interposer requires no calibration
- “Passive” tapping to avoid masking, hiding, or “cleaning up” electrical and/or link issues
- Low-cost, flexible, high-performance cabling for reliable analyzer to interposer connections
