AD5668 output 0 fix

Hi 

I am FAE in Japanese distributor.

Our customer evaluate AD5668.

But  AD5668 output fix 0V and does not change occasionally after power up.

Defect frequency is about 1 time in 10 times power up.

AD5668 has some register(ex. input register, DAC register, LDAC register,

Power down register, Clear Code register, Reference register).

Could you tell me what is default value after power on?

best regrads
