[1] Frequency is guaranteed across process, voltage and temperature from -400C to 850C.
[2] With high charge-pump current, +12dBm 100MHz sine reference
[3] Fractional FOM degrades about 3dB/octave for prescaler input frequencies below 2GHz
[4] Using 50MHz reference with VCO tuned to within one loop bandwidth of an integer multiple of the PD frequency. Larger
offsets produce better results. see the “spurious Performance” section for more information.
[5] Measured with the HMC704LP4E evaluation board. Board design and isolation will affect performance.
[6] Internal divide-by-2 must be enabled for frequencies >4GHz
[7] At low RF Frequency, Rise and fall times should be less than 1ns to maintain performance
[8] slew rate of greater or equal to 0.5ns/V
[9] Current consumption depends upon operating mode and frequency of the VCO
[10] Reference input disconnected
[11] Min/Max versus temperature and supply, under typical reference & frequencies & RF power levels
[12] slew > 0.5V/ns is recommended , see Table 6 for more information
[13] Operable with reduced spectral performance up to +7 dBm
