This parameter is programmable
(10) A specification in modeling PLL in-band phase noise is the 1/f flicker noise, LPLL_flicker(f), which is dominant close to the carrier. Flicker
noise has a 10 dB/decade slope. PN10kHz is normalized to a 10 kHz offset and a 1 GHz carrier frequency. PN10kHz = LPLL_flicker(10
kHz) - 20log(Fout / 1 GHz), where LPLL_flicker(f) is the single side band phase noise of only the flicker noise's contribution to total noise,
L(f). To measure LPLL_flicker(f) it is important to be on the 10 dB/decade slope close to the carrier. A high compare frequency and a clean
crystal are important to isolating this noise source from the total phase noise, L(f). LPLL_flicker(f) can be masked by the reference
oscillator performance if a low power or noisy source is used. The total PLL inband phase noise performance is the sum of LPLL_flicker(f)
and LPLL_flat(f).
(11) A specification modeling PLL in-band phase noise. The normalized phase noise contribution of the PLL, LPLL_flat(f), is defined as:
PN1HZ=LPLL_flat(f)-20log(N)-10log(fCOMP). LPLL_flat(f) is the single side band phase noise measured at an offset frequency, f, in a 1 Hz
bandwidth and fCOMP is the phase detector frequency of the synthesizer. LPLL_flat(f) contributes to the total noise, L(f).
