Genesys 2 Differential Contrlled Impedance Routing

Question

Hello,

I have a Genesys 2 board and was wondering if there is 100 ohm line to line controlled impedance routing for differential pairs that go to the HA, HB, and LA banks on the FMC connector.

Hi @SeanS,

Looking at the Genesys 2 schematic there is not a 100 ohm line to line controlled impedance routing for differential pairs that go to the HA, HB, and LA banks on the FMC connector. 

best regards,

Jon

The schematic shows that a differential pair constraint was added (two red eye looking probe thingies).  I should have looked here sooner.  But a colleague mentioned that the constraint may not have been used in the layout.  Do you know the person who laid out the board?  Perhaps he can confirm the 100 ohm line to line impedance?
