Note 3: Normalized Phase Noise Contribution is defined as: L
measured at an offset frequency, f, in a 1 Hz Bandwidth. The offset frequency, f, must be chosen sufficiently smaller than the PLL loop bandwidth, yet large enough
to avoid substantial phase noise contribution from the reference source. The offset chosen was 4 KHz.
