For this plot, a third order modulator with dithering disabled was used with a fractional denominator of 500000. The charge pump gain was 32X and the loop filter
components were C1 = 2.2 nF, C2 = 22 nF, R2 = 470 Ω. The internal loop filter components were C3_LF = 20 pF, C4_LF = 100 pF, R3_LF = 1 kΩ, R4_LF = 200
Ω. The VCO frequency is 3320.1 MHz. The OSCin signal was a 500 MHz differential LVPECL output of the LMK04033.

Ω. The VCO frequency is 3840.2 MHz, but the VCO Divider is set to two, so the RFout frequency is 1720.1 MHz. The OSCin signal was a 500 MHz differential
LVPECL output of the LMK04033.
