NOISE CHARACTERISTICS

dBc/Hz
1 Operating temperature range (B version) is –40°C to +85°C.
2 AVDD = DVDD = 3 V.
3 AC coupling ensures AVDD/2 bias.
4 Guaranteed by design. Sample tested to ensure compliance. Use of the PFD at frequencies above 104 MHz requires the minimum antibacklash pulse width enabled.
5 TA = 25°C; AVDD = DVDD = 3 V; RFIN = 350 MHz. The current for any other setup (25°C, 3.0 V) in mA is given by 2.35 + 0.0046 (REFIN) + 0.0062 (RF), RF frequency and REFIN
frequency in MHz.
6 The normalized phase noise floor is estimated by measuring the in-band phase noise at the output of the VCO and subtracting 20logN (where N is the N divider value)
and 10logFPFD. PNSYNTH = PNTOT – 10logFPFD – 20logN. All phase noise measurements were performed with an Agilent E5500 phase noise test system, using the EVAL-
ADF4002EB1 and the HP8644B as the PLL reference.
