DS90UB913A-Q1: PCB layout with long distance between IC and connector

Part Number: DS90UB913A-Q1

Hi team,

Our customers are considering to design 913A - 914A using STP or STQ.

There is a limit to the placement of parts, and the distance from the IC to the connector may be from 50mm to 100 mm.

The parts configuration is as follows.

  IC - AC Coupling capacitor - (ESD) - Common mode choke coil - ESD protection - Connector

We are making boards especially concerning EMC.

Can we extend the distance between which parts?

Or should not we extend the distance between which parts?

Please tell me if there are nodes that are likely to affect EMC.

If there is no particular influence as long as this wiring length, we will extend the ESD - connector that is most likely to stretch.

Best regards,

Tomoaki Yoshida
