DA9777 SPI

Hi,

 

We are using AD9777 for one of our tone generation applications.

I can see from datasheet that the SPI registers have some bits written in bold which are the default values.

but there are certain bits for example register 00h[4] is not having any default value, So this bit description says "sleep mode logic1 shuts down the DAC output currents" may i know if i have to program any of these registers before using the DAC for tone generation?

I want to use it 2 port mode, no pll. Do i need to set any SPI registers or the default values in the DAC should work as is?

 

thanks

Prasanthi
