(1) For optimal phase noise performance, higher input voltage and a slew rate of at least 3 V/ns is recommended

(2) Tested to 13.5 GHz, Guaranteed to 14 GHz by characterization

(3) PLL Noise Metrics are measured with a clean OSCin signal with a high slew rate using a wide loop bandwidth. The noise metrics model

the PLL noise for an infinite loop bandwidth as:

PLL_Total = 10×log( 10^PLL_Flat/10+ 10^{PLL_Flicker(Offset)/10}

PLL_Flat = PN1Hz + 20×log(N) + 10×log(Fpd/1Hz)

)

PLL_Flicker = PN10kHz - 10×log(Offset/10kHz) + 20×log(Fvco/1GHz)

(4) Charge pump mismatch varies as a function of charge pump voltage. Consult typical performance characteristics to see this variation.
