Driver AD9253 using ADA4937

I have designed a circuit by using an ADA4937-1. I used it to drive ad AD9253-125.

As shown in the picture attached, the input is a single ended Vpp = 1,6V.

The Vcm of the ADC is qual to 0,9V but, using this voltage as Vocm for ADA4937, the signal is clipped.

I would like to know whether it is possible to use a different value for as input to the driver (e.g. 1,3V), without altering the proper working of the ADC of if a different Differential ADC Driver must be used. (as input to the ADC)


Thank you very much,
