1. Table 2 - Loop Filter Values
The datasheet advises that the capacitor next to the VCO input (C3_LF in this case) should be at least 3.3
nF. The LMX2581 will certainly work for lower values, but this can cause phase noise degradation at
farther offsets if this capacitor is too small.

Burning in the Crystal Oscillator
The LMX2581 comes with a crystal oscillator on the board. This crystal oscillator was
chosen because it has good phase noise, standard package, and most importantly it is
readily available. However, it is not necessarily the most accurate and does require to be
burnt in. This is not done before the boards are shipped. To burn in the crystal, all one has
to do is hook up the evaluation board and leave power applied.
This improves crystal
stability and also phase noise at low offsets below 1 kHz.
