Hello support team,


Please advice me about below questions related to AD9257.


1. I advised that Digital-reset(as shown below) after powerup in order to initialize a core of ADC.
   SPI_Write(0x08,0x03);#Digital Reset
   SPI_Write(0x08,0x00);#Normal Operation
   After the digital reset, it is required to delay  until normal operation and setting of register?


2. Soft reset is used for initialize of register, so isn't it need when powerup?


3. Have each digital data output phase gap? (ADC-A to ADC-H)
   If yes, how long shift?
