Hi,

 

Could you please reply to following questions ?

 

a) ADAU1452 I2C Slave timing spec of tDH (data hold time) is 0.9 us (min) in datasheet, but is this correct ?

We thought data hold time on standard I2C specification is typically 0 us (min). 

If it is truly 0.9 us, it is rather hard condition for us to achieve, so please make sure.

 

b) In case 0.9 us is correct, if real timing of tDH is > 0 us or >0.9 ns(nano second), does it consequent to any communication failure ?

 

Best Regards,
