Hi,

I am using the above mentioned Redriver for PCIe signals. can I get assistance how to design EQA0, EQA1, EQB0, EQB1 and DEMA, DEMB pins in Pin mode.

Can I get a sample design how to design the IC in Pin mode.

Regards,

Swetha

Hi Swetha,

The User Guide has a schematic of the DS80PCI102.

www.ti.com/.../ds80pci102evk

For EQ and DEM I recommend staying within the following range in PCIe Gen2 or Gen3 applications.

EQ: Pin settings from datasheet (Level 1 - Level 5)

DEM: Pin setting which keeps DEM at or below -3.5dB. For most PCIe applications in Gen3 a 0 dB setting works best.

Regards,

Lee

Hi Lee,
Thank you for the reply.
Our design has a fixed trace length of 15inches, based on that we have selected below mentioned settings:
EQ: Level 6
DEM: Level 4
Would you still recommend EQ: from Level1 - Level5 and DEM: Below -3.5dB.

Regards,
Swetha

Hi Swetha,
Yes start with minimum values for both.
