In order to achieve best phase noise performance 1V peak level is suggested. 2. The frequency step is related to the PFD input frequency as follows: - Fstep = FPFD for direct output - Fstep = FPFD/2 for divided by 2 output - Fstep = FPFD/4 for divided by 4 output 3. See the relationship between ICP and REXT in Section 5.7: Charge pump. 4. The level of the spurs may change depending on PFD frequency, charge pump current, selected channel and PLL loop BW. 5. Guaranteed by design and characterization. 6. Frequency jump from 1950 to 1800 MHz; it includes the time required by the VCO calibration procedure (7 FPFD cycles with FPFD=400kHz). Table 5.
