SKY73100 Electrical Characteristics (Note 1) (VCC = 5 V, TC = 25 °C, Charge Pump Current = 600 µA, FREF = 52 MHz, Reference Input Divider = 8, Prescale Divider = 8/9, Unless Otherwise Noted) Parameter Symbol Test Conditions Min Typical Max Units Oscillation frequency 865 960 MHz Reference frequency 13 52 MHz Phase detector frequency 6.5 MHz PLL loop bandwidth 25 kHz Output level 0 dBm Output impedance 50 Ω Output VSWR *** TBD *** – Reference frequency input (FREF) impedance 470 Ω Harmonic suppression –20 dBc Integrated phase noise 100 Hz to 100 kHz 1 degrees RMS Single sideband phase noise offset: @ 1 kHz @ 5 kHz @ 10 kHz @ 200 kHz @ 400 kHz @ 600 kHz @ 800 kHz @ 1.8 MHz @6 MHz –91 –90 –90 –127 –140 –145 –148 –153 –165 dBc/Hz dBc/Hz dBc/Hz dBc/Hz dBc/Hz dBc/Hz dBc/Hz dBc/Hz dBc/Hz PLL-reference spurious suppression –100 dBc Frequency settling time Within ±2 kHz 250 µs Phase settling time Within ±5 deg 300 530 µs Peak phase error 5 degrees Current consumption 120 mA Note 1: Characterized performance may change if the SKY73100 is configured differently than the test conditions specified here. This characterization used a 6.5 MHz fixed comparison frequency for the PLL phase loop filter. The PLL synthesizer is programmable up to a maximum comparison frequency of 26 MHz but with degraded performance. Table 6.
