Test Conditions/Comments1
−10 dBm min to 0 dBm max; for lower frequencies,
ensure slew rate (SR) > 400 V/μs
For f < 10 MHz, use a dc-coupled CMOS-compatible
square wave, slew rate > 25 V/μs

@ VCO output
@ 5 kHz offset, 25 MHz PFD frequency
1 Operating temperature for B version: −40°C to +85°C.
2 AC coupling ensures AVDD/2 bias.
3 Guaranteed by design. Sample tested to ensure compliance.
4 This figure can be used to calculate phase noise for any application. Use the formula –213 + 10log(fPFD) + 20logN to calculate in-band phase noise performance as seen
at the VCO output. The value given is the lowest noise mode.
5 The phase noise is measured with the EVAL-ADF4156EB1 evaluation board and the Agilent E5500 phase noise system.
6 fREFIN = 100 MHz; fPFD = 25 MHz; offset frequency = 5 kHz; RFOUT = 5800 MHz; N = 232; loop B/W = 20 kHz, ICP = 313 μA; lowest noise mode.
