ADUM1401: Can I increase max data rate to 2Mbps and will this compromise pulse width distortion spec ?

Q

The data sheet for ADuM1401 specifies that the maximum data rate for
ADuM1401ARWZ is 1Mbps to guarantee a maximum pulse width distortion of 40ns.
Could ADuM1401ARWZ support 2Mbps data rate if the 40ns pulse width distortion
spec can be compromised and if so what is the maximum pulse width distortion
for 2Mbps data rate for this device?

A

The maximum signal data rate that can be supported by the ADuM1401ARWZ is
1Mbps. You should use the ADuM1401BRWZ, it can support a maximum data rate of
10Mbps.
