6.15 Typical Characteristics: Linearity Sweeps
NSD at 70 MHz offset from tone, typical values at TA = +25°C, minimum and maximum values over operating free-air temperature range, typical supply voltages, fCLK = 12 GHz, IFS_SWITCH = 20.5 mA, single tone amplitude = 0 dBFS, Dither and DEM enabled, DEM_ADJ = 1 below 750 MHz and 0 above 750 MHz, unless otherwise noted. SFDR/harmonics measured between 0 and fCLK/2 when fOUT < fCLK/2 and fCLK/2 and fCLK when fOUT > fCLK/2.
