I will evaluate the ADF4106 with analog lock detect.
At the our PLL setting for high PFD, ALD voltage is low.
ALD voltage:high is about 1.2V @ VDD=3.0V
I want to keep the locked voltage level of ALD high more than 1.6V at least.
I will decrease the pull-up resistor for increase the ALD.
What is the sink current limit value, for the N-channel, open-drain, analog lock detect?
