About ADN4612 use issues

when i use the ADN4612,i found the differential line output level is not same:

the ADN4612 pin out as follow:

pin 24/25  are OP0/ON0,the output level is 1.67V/2.43V

pin 27/28  are OP1/ON1,the output level is 1.62V/2.43V

pin 30/31  are OP2/ON2,the output level is 2.25V/1.86V

pin 33/34  are OP3/ON3,the output level is 1.67V/2.43V

pin 36/37  are OP4/ON4,the output level is 1.9V/2.16V

pin 39/40  are OP5/ON5,the output level is 1.9V/2.16V

 

1:why the voltage is not different between the differential line(OP/ON)?

2:why the voltage is not different between the port to port (for example:OP1/ON1 and OP2/ON2)?

3:the OP0/ON0,OP1/ON1,OP3/ON3 noise is low,and the OP2/ON2,OP4/ON4,OP5/ON5 noise is very high.

 

please help us to see what the problem is ,thanks.
