*) Type means: A = 100% tested, B = 100% correlation tested, C = Characterized on samples, D = Design parameter
Note:
1. The phase detector’s phase-noise contribution to the VCO’s frequency spectrum is determined by the operating frequency
of the phase detector divided by 4 according to the fractional-N technique (regularly: 16 kHz).
