[ LMX2582 ] Input Amplitude, Valid Termination for Single-End input and Single-End Output
Hi,
Can you help me to clarify the definition of input amplitude requirement?
If above is correct, it seems that the oscillator which suggested in the typical application drawing has larger amplitude than specification.
Also, if we use single-ended input to OSCinP, what is the valid termination of OSCinN?
As my understanding, OSCinN should be terminated via Cin(1uF, same as OSCinP) and 50ohm resistor to GND. It's not clear for me that having R22(18ohm) and R21(68ohm).
On top of that, if customer use only RFoutAP, do you suggest to terminate RFoutAM with L3, R32(49.9ohm), C17(100pF) and R33(49.9ohm) as illustrated?
Thank you for your support in advance.
Regards,
Ken
