Note 3: A slew rate of at least 100 V/uS is recommended for frequencies below 500 MHz for optimal performance.
Note 4: For Phase Detector Frequencies above 20 MHz, Cycle Slip Reduction (CSR) may be required. Legal divide ratios are also required.
Note 5: Refer to table in Section 2.4.2 RF_CPG -- RF PLL Charge Pump Gain for complete listing of charge pump currents.
Note 6: In order to measure the in-band spur, the fractional word is chosen such that when reduced to lowest terms, the fractional numerator is one. The spur offset
frequency is chosen to be the comparison frequency divided by the reduced fractional denominator. The loop bandwidth must be sufficiently wide to negate the
impact of the loop filter. Measurement conditions are: Spur Offset Frequency = 10 kHz, Loop Bandwidth = 100 kHz, Fraction = 1/2000, Comparison Frequency =
20 MHz, RF_CPG = 7, DITH = 0, and a 4th Order Modulator (FM = 0). These are relatively consistent over tuning range.
Note 7: Normalized Phase Noise Contribution is defined as: LN(f) = L(f) – 20log(N) – 10log(fCOMP) where L(f) is defined as the single side band phase noise
measured at an offset frequency, f, ina1Hz 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. Measurement conditions are: Offset Frequency = 11 kHz, Loop Bandwidth = 100 kHz for
RF_CPG = 7, Fraction = 1/2000, Comparison Frequency = 20 MHz, FM = 0, DITH = 0.
