About the OpenPCIE PCB
OpenPCIE is an open source PCB design by chili-chips-ba, published on GitHub under the BSD-3-Clause license. It is a 4-layer board measuring 179.1 × 92.3 mm, with 170 components from 43 distinct parts.
Other key parts include the TPS54KC23RZRR, SN74LVC244APWR, LP5907MFX-3.3/NOPB, PI6CG18801ZLIEX and RY3420. By type, the board carries 86 capacitors, 32 resistors, 11 connectors, 11 jumpers, 6 ICs and 6 test points.
From the project
Peripheral Component Interconnect (PCI) has taken the Express lane long ago, moving to xGbps SerDes. Now for the first time in opensource on the Host side too. Our project roots for the Root Port in 4 ways: |1|openRTL |2|openBFM with unique SIM setup, way faster than vendor's |3|openSW stack |4|one-of-a-kind open backplane.
The board is designed for flexible PCIe system development and testing, featuring two distinct logical islands: - (1-to-1) 4-lane Direct connection - (1-to-4) 1-lane Switched connection.
- Modular Design: - Two independent “islands” for different PCIe topologies. - Flexible Connectivity: - Supports standard PCIe Slots and M.2 (M-key, PCIe) connectors. - Power, Clock and Reser generation: - Single 6-pin PCIe power connector supplies the entire board (up to 70 W total). - Integrated 100 MHz REFCLK generator and reset (PERST#) distribution circuits. - Innovative RC Connector Design: - Allows…
