LMX2595: LMX2595 PHASE NOISE ISSUE

$

Part Number:LMX2595

Hello

I have 2 queries.

1. In the evaluation board datasheet, for the loop filter assembled, the bandwidth mentioned in 285 KHz, but in simulation in PLLatinum why is bandwidth getting simulated ad 49.5Khz... I have attached the 2 images. Please clarify

The second query is same as earlier.... As per simulation file posted above the phase noise is -94 at 1K and 10K offsets... But practically I am measuring 80 at 10MHz ref.... At 100 MHz ref... the simulation and practical results are matching.... What might be the issue at lower PFD.   Please clarify. I am attaching the phase noise of the source and the measured value of LMX2595 along with TICS PRO settings...
