I am using the part ASV-12.000MHZ-EJ-T for generating a 12MHz Clock signal on my custom PCB. The following screenshot is the circuit. (Please ignore the part number in the screenshot, I have replaced that part with the part mentioned before).
When I try to observe the output of the crystal using oscilloscope at XIN, I see the following waveform.
Its doesn't appear like a sinusoidal waveform, instead it looks like a capacitor charging and discharging waveform.
I have tried the following to see if the waveforms becomes sine
1. replaced R189 with 0 Ohm Jumper - No change
2. Varied the load capacitances between 7.5 pF tthrough 45 pF - No change
Can anyone please have a look at this and let me know what could be the issue.
