We are implementing a design with two AD9953 and we want to know if we can daisy chain the SPI Interface between the two DDS.
Just to be clear, what we want is,
1) Processor SPI_MOSI -> DDS1 SPI_SDIO
2) DDS1 SPI_SDO -> DDS2 SPI_SDI
3) DDS2_SDO -> Processor SPI_MISO
There does not seem to be any mention regarding daisy chaining.
Kindly let us know if the above is possible and can be used to access both DDS SPI Interfaces.
Also, Readback functionality from DDS is not strictly required.
Thanks in advance.
