I want to configure AD9680 using SPI. For example, I want to configure register 0x570 to 0x8B.
I need 24 SCLK clock period.
the SDIO is 0(write)000 0101 0111 0000 1000 1011 contiously.
Am I right?
If you assert the PDWN pin while the part is still powered ON, the SPI port will be active and you can access registers.
Please refer to datassheet table 26 and table 27 for supported modes.
Also refer to the register map 0x570 to learn how to configure the L, M and F values.
For information on programming SPI you may refer to figure 4 on page 11 of the datasheet. you may also refer to the SPI standard here https://wiki.analog.com/resources/technical-guides/adispi
Umesh, for parts such as AD9234 does the SPI port and register access remain active if you assert PowerDown?
