Hello,

 

I have a question about serial interface of AD5760.

http://www.analog.com/en/digital-to-analog-converters/da-converters/ad5760/products/product.html

 

Pls refer to the Figure2.

 

The datasheet describes,P.21
" If more than 24 falling SCLK edges are applied before SYNC  is brought high, the input data is also invalid".

 

What does "the input data is also invalid" mean?.

In that case,does the data of DACREG change?. 

 

Regards,
Kou
