Impedance Control EMC Signals LPC4370

The AN11508 EMC Application Note calls for the following on page 21:

 

1) CLKx = 0.007" at  Zo=65-67ohms
2) All other EMC signals = 0.004" at Zo=80ohms
3) Matched length all EMC signals aside from CLKx.

 

Anyone used these specifications? I never used any impedance other than 50ohms for SDRAM signals before.
