We are interested in using the reference CLK_OUT function to help save several buffering parts to send the clock to our FPGA baseband. However we need for this output to be functional at all times, including during the Sleep state. My FMcomms2 board shuts off CLK_OUT in Sleep. I've reviewed the register map (UG-671) and do not see any settings for keeping this on during Sleep.
Is there any way to keep CLK_OUT on during Sleep?
