Question on the PCN of ADuM1285


I found a PCN for ADuM1285 from ADI web.

It shows data sheet change,

1) Increased maximum propagation delay specification on C grade models(ADuM128xWCRZ).

Is this only for the C grade models of ADuM128xW part or includes all C grade models of ADuM128xWCxx and ADum128xCxx ?
