ADF4106 open-drain sink current max value using the ALD?

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?
