¹Operating temperature: −40°C to +125°C.

²Guaranteed by design. Sample tested to ensure compliance.

³This specification can be used to calculate phase noise for any application. Use the formula ((Normalized Phase Noise Floor) + 10 log(f_PFD) + 20 logN) to calculate

in-band phase noise performance as seen at the VCO output.

⁴The PLL phase noise is composed of flicker (1/f) noise plus the normalized PLL noise floor. The formula for calculating the 1/f noise contribution at an RF frequency (f_RF)

and at an offset frequency (f) is given by PN = PN_{1_f}+ 10 log(10 kHz/f) + 20 log(f_RF/1 GHz). Both the normalized phase noise floor and flicker noise are modeled in ADIsimPLL.

⁵The phase noise is measured with the EV-ADF4159EB3Z and the Rohde & Schwarz FSUP signal source analyzer.

⁶f_REFIN= 100 MHz; f_PFD= 100 MHz; offset frequency = 50 kHz; RF_OUT= 12,002 MHz; N = 120.02; loop bandwidth = 250 kHz.
