PI7C9X20505GPBNDE

PI7C9X20505GPBNDE is a high‑speed signal switch/multiplexer from Diodes Incorporated (Pericom lineage) in the PI7C9X family. It functions as a crosspoint that routes differential high‑speed lanes between ports on a board (typical use: PCIe, USB, DisplayPort/SerDes signals). It’s used to implement lane switching or muxing with low on‑resistance and fast, predictable timing, often with a simple GPIO or control interface. Features usually include supports for multi‑gigabit SERDES rates, ESD protection, and a small RoHS‑compliant package; exact capabilities (lane count, data rate, supported protocols, power pins) depend on the specific device variant. The GPBNDE suffix encodes packaging and reel/lead options. For precise specs, pinout, and electrical characteristics, consult the official PI7C9X20505GPBNDE datasheet on Diodes Incorporated’s website or authorized distributors. If you want, I can help locate and summarize the exact datasheet.

- Pin count: 28 pins (QFN-28 package)
- Function: PCIe switch/crosspoint mux (PCIe lane routing device) from the PI7C9X family used to route PCIe lanes between devices/connector ports.

- Manufacturer: Diodes Incorporated. The PI7C9X20505GPBNDE comes from the PI7C family that originated with Pericom Semiconductor, which Diodes acquired.
- Company type: A global semiconductor company that designs and manufactures analog, mixed-signal and logic ICs, including high-speed interconnect solutions (PCIe/USB/HDMI).

PI7C9X20505GPBNDE is a PCI Express switch/re-timer family device. Common application areas include:
- PCIe port fan-out and bridging: root complex to multiple endpoints (NVMe, SSDs, NICs, GPUs, FPGAs).
- Backplanes and mezzanine cards in servers, workstations, and networking gear.
- Signal integrity extension: retimer/repeater to sustain PCIe performance over longer traces, cables, or connectors.
- Embedded/industrial systems and storage appliances needing multiple PCIe interfaces in compact form factors.
- Automotive/industrial networks using PCIe for high-speed interconnect between modules or ECUs.
