EVAL-AD1937AZ

Hi,

may I ask one simple question?

1.when I use AD1937 EVB, coudl I do a loop back play mode that AN1or AN2  input and DAC1 or DACx output directly?

if could, how can I seting, is that AUX mode?

2. if I could use stand along slave mode,in this mode,  AN1 input analog should be Serial audio to Optical TX output, right?

then I connect optical TX to RX in board, RX would play in 4DAC output, right?

thanks!

Br,

Hans
