Floor FOM of HMC826LP6CE is -227dBc/Hz@Frac and -229dBc/Hz@Inte.
What is Flicker FOM of HMC826LP6CE?
Flicker FOM is -268dBc/Hz (typical) for both integer and fractional-n modes. Low frequency references with slow slow rates, typically 10MHz sine waves, will degrade flicker and floor FOM by about 5 dB. This is caused by an increase in reference buffer noise when operating with slow slew rate input signals and is the reason we include the following note in the datasheet.
