Other Parts Discussed in Thread: DS80PCI402
Hi Sir,
I plan use LVPE801 application PCIe 3.0. Some issue need you help!
This is a PCIe gen3 x4 project
Below is our system trace length and we follow datasheet’s capacitor and resister value to verify, but the test result : PCIe gen3 x4 riser card can’t be detect.
Do you have idea how to fine tune the value?
We current verification as below
1. Bypass LVPE801 à function is ok.
2. Config DE/QE pull high à issue still have.
3. Add 1uF/10nF cap close VCC of LVPE801 à issue still have.
4. Check supply current 40mA of unit LVPE801 -> 16 pcs LVPE801, we provide 2A for use.
