Hi,

Do you have any comparison data on signal quality differences between the Redriver DS320PR810 and the Retimer DS160PT801?
Are there any routing length limitations in the PCB layout? Thank you.

    Hi Jeff,

    Is there a specific data point you are looking to compare between the devices' signal quality? Both the signal quality differences and the routing length limitations will be affected by the generation of the device and the PCB material. The DS320PR810 is a PCIe 5.0 device, while the DS160PT801 is PCIe 4.0. Do you have a data rate requirement for your design?

    Best regards,

    Greg
