Hello,
I'm seeing a strange output from my TRF3722 device. It's configured to generate a tone at 3GHz, using a reference of 50MHz. The output centered at the correct frequency (3GHz) but its generating about 30MHz of equally spaced tones. I've double-checked that all of the voltages are correct and that soldering of the part is good.
I am seeing the lock detect as high, but this is what the loop filter's VTUNE signal looks like:
I have this same design on a few other boards, but I haven't this issue. Have you seen anything like this before, or have an idea of what could be happening?
