A.9.2. PCIe Interface
The PCIe* x4 Gen2 Hard IP with CvP is implemented in this development kit. The position of the PCIe* channels is fixed by the hard IP. This development kit is a PCIe* add-in card. The PCIe* interface is configured to End-Point.
The PCIe* interface has the following signals:
- Transceivers, x4, up to 5 Gbps
- PCIE_REFCLKp/n, 100 MHz from PCIe* system
- PCIE_SMBUS, 3.3 V level-translated to 1.8 V with U18
- PCIE_PERSTn, 3.3 V level-translated to 1.8 V with U17
- PCIE_WAKEn, 3.3 V level-translated to 1.8 V with U17, reserved
The PCIe* width can be selected with Jumper resistors:
- R506 installed, x1 mode
- R507 installed, x4 mode, this is the default mode
There are three power rails from PCIe* golden finger connector:
- +12 V, ±8%, up to 75 W, is used as power of the board
- +3.3 V, ±9%, up to 10 W, is not used on this board
- +3.3 Vaux, ±9%, 375 mA max, is not used since wakeup is not supported
