DS80PCI800: cable definition

GARETH OU

Part Number: DS80PCI800

DS80PCI800SQE applications are as follows
1. ADD IN CARD
2. FPC/ FFC CABLE
3. DAUGHTER CARD
4. Mother Board
I want to use Gen3 repeater at ADD IN CARD (yellow box) and DAUGHTER CARD (yellow box)
My question is how many mm does the FPC/FFC CABLE need to maintain Gen3 speed?

Hi Gareth,

This depends on your media insertion loss. DS80PCI800 can compensate for 36dB loss so as long as your media loss is within this range we should be fine.

Before starting your schematic, it would be a good idea to do some preliminary signal integrity analyses. We can provide IBIS-AMI model so you can do this study. Please use link below to request this model:
