概述

Description

PI3PCIE3412ZHE is a PCIe Gen3 signal integrity device from Pericom (now Renesas) in the PI3PCIE family. It acts as a PCIe switch/re-timer to help fan-out or route PCIe links between a host and one or more endpoints and to restore signal integrity over longer PCB traces or connectors. In short, it enables reliable PCIe wiring when routing signals across boards or to multiple devices.
Key points:
- PCIe compatibility: Gen3 (up to 8 GT/s); supports standard PCIe voltage levels.
- Function: signal re-timing/re-shaping and/or port routing to improve integrity and flexibility of PCIe layouts.
- Package: ZHE indicates RoHS-compliant packaging; check the datasheet for exact package type and pinout.
- Applications: motherboards, PCIe add-in cards, or any board needing reliable PCIe signal integrity and/or fan-out.
For exact port counts, lane configuration, timing, power, and layout guidelines, refer to the official PI3PCIE3412ZHE datasheet.

Package

QFN (leadless) package. For the exact pin count and footprint, please refer to the PI3PCIE3412ZHE datasheet.

Pinout

Pin count: 20 pins (QFN20, ZHE package).
Function: PCIe 3.0 retimer/redriver device (PI3PCIE3412ZHE) used to retime and route PCIe differential pairs between host and endpoint, improving signal integrity on PCIe links.

Manufacturer

Manufacturer: Diodes Incorporated (Diodes Inc.), which acquired Pericom Semiconductor (the PI3PCIE系列 originated there).
What kind of company: a global semiconductor company that designs and manufactures integrated circuits—diodes, analog, logic, power-management and mixed-signal ICs for communications, computing, consumer and industrial markets.

Application

Application areas: PCIe switch/fan-out for expansion and backplane interconnects in embedded, mobile, desktop and server systems; NVMe/storage and accelerator interconnects; docking stations and multi-card chassis; telecom/networking equipment requiring PCIe fabric; industrial/automotive embedded systems with PCIe routing and re-timing.

Equivalent

PI3PCIE3412ZHE is a PCIe Gen3 2-lane retimer/re-timer from Pericom (Renesas). Potential equivalents (exact cross-reference depends on function and features) include TI PCIe retimers (DS80/DS90 series), Parade Technologies PCIe retimers, Analogix PCIe retimers, and other Renesas PI3PCIe parts. For exact cross-references, use distributor tools (Digi-Key, Mouser) or contact Renesas/Pericom.
