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.
