PI3PCIE3412ZHE

PI3PCIE3412ZHE is a PCI Express switch/re-timer from the PI3PCIE family (Pericom/Renesas). It fans out one PCIe upstream link to two downstream links, enabling a host/root complex to connect to two PCIe devices while preserving signal integrity.
Key points:
- PCIe topology: 1 upstream port to 2 downstream ports (x1/x2 configurable as needed).
- Speed: designed for PCIe Gen3 performance (up to 2.5 GT/s per lane) with on-chip retiming/equalization.
- Functions: signal conditioning, lane mux/demux, and support for proper PCIe timing/power sequencing.
- Package: ZHE lead-free package.
- Typical uses: motherboard/embedded boards or PCIe bridge applications where a single host needs to connect to multiple endpoints.
For exact specs (pinout, supply, jitter/equalization details, thermal/power, and electrical characteristics), consult the official PI3PCIE3412ZHE datasheet and product selector from Renesas/Pericom.

Direct equivalents depend on the device’s exact function (retimer, repeater, switch) and lane count. PI3PCIE3412ZHE is a Pericom PCIe 3.0 device, but there isn’t a universal drop‑in cross reference. Please share the datasheet/link or confirm: PCIe generation (1/2/3/4), number of lanes (x1/x2), and whether it’s a retimer, repeater, or switch. With that, I can provide precise cross references from Renesas, TI, Broadcom, etc.

Here are the typical features of PI3PCIE3412ZHE (PCIe switch/re-timer from Pericom):
- PCIe Gen3 compliant, up to 8 GT/s per lane
- 2 downstream ports and 1 upstream port (configurable topology)
- Non-blocking switch fabric with per-port isolation
- Integrated re-timer/equalization for robust signal integrity
- ASPM/L1 power management support; hot-plug capable
- I/O: 3.3V tolerant; core/source voltage compatible (typical low-power footprint)
- Small package with Pb-free, halogen-free (ZHE) packaging
- Designed for embedded/mobile applications with low power consumption
Note: for exact port configuration, electrical details, and timing specs, please refer to the official datasheet.

PI3PCIE3412ZHE is a PCIe switch from Pericom (Renesas). It provides a 3-port PCIe switch: 1 upstream port and 2 downstream ports to fan out PCIe lanes. The ZHE package is a small QFN, typically 20 pins. Note: exact pinout/pin count can vary by package variant; please verify with the datasheet for the specific package you have.
