With the LMX2572LP, is there any way to put the pin into the MUXout pin 20 into a High Impedance state?
The MUXout pin can be set between lock detect and register readback. In register readback, it behaves like SPI SDO. In order to have multiple devices on the SPI bus, the LMX2572LP MUXout needs to be able to be placed into a High Impedance state. However, I do not see anything in the data sheet that talks about the MUXout pin being able to go high impedance. In Figure 1 Serial Interface Timing Diagram, while CSB is high, MUXout is still held low, not placed into a high impedance state as would be expected with an SPI compatible device.
Thank you
