Description
PI3PCIE3412AZHEX is a PCI Express switch in the PI3PCIE family (from Renesas/Pericom) that fans out one PCIe upstream link to two downstream ports. It lets a host processor connect to two PCIe devices behind a single upstream connection, enabling PCIe expansion with a small footprint.
Key points:
- PCIe switch architecture: single upstream, two downstream ports
- Supports PCIe Gen1/Gen2 operation (speeds up to 5 GT/s per lane, depending on variant)
- Typical features: non-blocking switch fabric, hot-plug/power-management support, standard PCIe signaling
- Package: AZHEX, RoHS-compliant, suitable for compact board layouts
- Applications: embedded systems, single-board computers, automotive and industrial equipment needing PCIe expansion
For exact electrical specs, pinout, timing, thermal characteristics, and design guidelines, refer to the official datasheet and application notes from Renesas/Diodes Inc.
