Dear Analog,
the ADC AD9484 features a soft reset function, which is started by setting the Soft reset bits in the CHIP_PORT_CONFIG 00h register.
1. How much time the soft reset function takes? It is not specified nowhere I believe. We did not implement the read-out functionality in our code, so we would like to start the Soft reset and wait for it to finish. So how long we need to wait?
2. Is a write to the CHIP_PORT_CONFIG 00h register activated immediately (i.e. for the soft reset function) or only after the DEVICE_UPDATE FFh write?
3. When de-asserting the PWDN pin from high to low, to start a normal operation, how much time AD9484 needs to get fully operational (i.e. to accept the programming via SPI)?
Many thanks!!!
Best regards, Leon
