Hello.I have a VCO with +4dbm output at 50 ohm load. What is the min and max input sensitivity of RF IN1 pin 15 OF TSA5511 and what is its impedance?I am thinking of using a resistor attenuator of -5db to feed pin 15 .

In the past when i was feeding pin 15 with -7dbm it wouldnt lock,it needed -6dbm at least to lock.

In the datasheet says input sensitivity minimum 12mV ,maximum 300mV.Does that mean that for a TSA5511 can have minimum sensitivity 12mv and another TSA5511 can have a minimum sensitivity of 200mV?

"minimum 12mV ,maximum 300mV" is the range of the input level, which can be anywhere between those values.
