66AK2H14: SerDes/Serial rapid IO routing technique

Part Number: 66AK2H14

Hello,

I'm wondering how it possible to route the serial rapid IO differential lines for a long distance in the FR4 material PCB? since it's high frequency line 2.5GHZ (5gbps).

Regards,
Snir

    Snir,

    Please refer to the KeyStone II Architecture Serializer/Deserializer (SerDes) User's Guide (SPRUHO3A) available at the link below for general guidance.  What do you refer to as 'long distance'?  SRIO is intended for board-to-board operation across a backplane so it is able to be routed over significant distance - up to 40 inches under ideal conditions.  Of course, connector type and quality and PCB material and stack-up all significantly affect the signal loss.  Final validation will require robust 3D analysis of the PCB routing.
