LMK03001: OSCin Input Impedance

Hello,

[Q1]

Please tell me the input impedance for OSCin.

The input can be considered high impedance and capacitive.  We traditionally will terminate for differential using a shunt 100 ohm termination, then ac coupling caps, then input pins as illustrated on Figure 8-1 of datasheet.  Is there some specific matching being attempted?

Can you give us the equivalent circuit for OSCin ?

I can check about this.

[Q3]

Do you have any data of reflection performance such as S11 or Return Loss for OSCin ? 

I do not have any of these plots.
