We are attempting to work with the HMCAD1520 according to the device datasheet. However, it appears that whenever we modify the device setup (such as the number of channels, frequency divider, etc.) and initiate a power down/power up sequence as instructed by the datasheet, the device becomes unresponsive, resulting in no data output and no output clock (FCLK).
It's the same with SPI commands or when using the the PD pin.
is there a solution for that?
