Other Parts Discussed in Thread: DS80PCI402

Dear all,

I would like to take your answer / recommendation about following.

■CHECK 1

I want to achieve same function like 89HP0504P (IDT).

Therefore I will choose DS80PCI402.

Is this correct?

■CHECK 2

I think that choice of cable and connector is important factor because of impedance matching.

What is the recommend cable and connector?

The length of cable will be 1 m (max 2 m).

Best regards,

    Hi Takao,

    Yes the DS80PCI402 offers a similar function to the IDT device.  The DS80PCI402 is an 8-channel device instead of 4 channels for IDT.

    Yes the choice of cable impedance is important.  Either 85 ohm or 100 ohm cable assemblies and connectors will work with the DS80PCI402.  The board impedance should be designed to match with the cable and connector impedance.  Any cables and connectors rated for PCIe 3 will work well

    Regards,
