[1] the lower limit of operation is limited by off-chip aC coupling. the size of the aC coupling should be chosen to have insignificant impedance

relative to the 3.6kohm input impedance of the part, and any termination impedances on the evaluation board (50ohm by default).

[2]reF and VCo inputs should be aC coupled to HMC1031Ms8e. Peak Input level should not exceed VCC+0.4 V with respect to GnD.

[3] Pll may lock in the voltage range of 0.2 to VCC - 0.4 V. However, the charge pump gain may be reduced. see Figure 9 CP Compliance

[4] see Figure 15, 16 for addional Flicker FoM and Floor FoM data.

[5] See Figure 10 for additional supply current data. Base Frequency 100MHz, Base VCC: 3.3V, 0.8 to 1mA/V, Base PFD current: 1.8 mA, 8 μA/

MHz Base DIV current: 1.15mA, 15 μA/MHz. For example, the device current for a 10 MHz ref and 50 MHz VCO at 3.0 V VCC can be calculated as

PFD Current delta = (10-100)*8e-6 = -0.72, DIV current delta = (50-100)*15e-6=-0.75 ma, Device current = (1.8-0.72)+(1.15-0.75)=1.48 ma at 3.3V

VCC

at 3 V VCC device current would be approx: 1.48 - 0.85e-3*(3.3-3.0) = 1.225 ma

[6] In Power down mode, the reF/VCo inputs and charge pump outputs are tri-stated. the power down leakage current is measured without any

signal applied to HMC1031Ms8e.
