1 Operating temperature range is from –40°C to +85°C.
2 The prescaler value is chosen to ensure that the RF input is divided down to a frequency that is less than this value.
3 fREFIN = 26 MHz; fSTEP = 200 kHz; fRF = 900 MHz; loop BW = 40 kHz.
4 fREFIN = 13 MHz; fSTEP = 200 kHz; fRF = 1850 MHz; loop BW = 60 kHz.
5 Calculated from the phase noise measured at 5 kHz with a 60 kHz loop BW. Increased noise contribution from the differential amplifier if the loop BW is reduced.
TIMING CHARACTERISTICS
AVDD = DVDD = 3 V ± 10%, VP1, VP2 = 5 V ± 10%, VP3 = 5.35 V ± 5%, AGND = DGND = GND = 0 V, RSET = 2.4 kΩ, dBm referred to
50 Ω, TA = TMIN to TMAX, unless otherwise noted.
