Hi,
I'm planning to use HS3SS3411 as PCIe Gen1 signal switch
and I have questions about HD3SS3411 layout.
We are planning 3 connection cases of HS3SS3411.
The connection is as follow:
////////////////////////////////////////////////////////////////////////////////
Case#1: Use one HDS3SS3411, PCIe RC(PHY) - HD3SS3411 - PCIe EP(PHY)
Case#2: Use two HDS3SS3411, PCIe RC(PHY) - HD3SS3411 - HD3SS3411 - PCIe EP(PHY)
Case#3: Use three HDS3SS3411, PCIe RC(PHY) -HD3SS3411 - HD3SS3411 - HD3SS3411 - PCIe EP(PHY)
////////////////////////////////////////////////////////////////////////////////
We want to know the following creepage distance of PCB pattern
in each above cases(#1,#2,#3).
1. creepage distance(inch or cm) between PCIe RC(PHY) and edge connector
2. creepage distance(inch or cm) between PCIe RC(PHY) and PCIe EP(PHY)
3. creepage distance(inch or cm) between edge connector and PCI EP(PHY)
In HD3SS3411 datasheet page.13, there are layout guidline.
But we could not find the information about creepage distance of above cases.
best regards,
g.f.
