I am using an ADF4360 in a transceiver and it's causing spurs on my transmitter. In testing we've found that they go away if I turn off the ADF4360. However we need to be able to turn it back on quicker than the <600us discussed on the data sheet. How quickly can it be woken up (is it nearly 600us or is it a lot less than 600us)? Are there any tricks for speeding up this process? I don't suppose the MUTE function (used for the MUTE-TILL-LOCK-DETECT function) can be controlled independently?
