TUNING VOLTAGE (V)

[1] Both Aux. LO and MOD LO Gain Set to ‘3’ (Max Level), both Aux. LO and MOD LO Buffer Enabled, measured from Auxiliary LO Port.

[2] RMS Jitter data is measured in fractional mode using 50 MHz reference frequency, from 1 kHz to 100 MHz integration bandwidth.

[3] Measured from a 50 Ω source with a 100 Ω external resistor termination. See PLL with Integrated RF VCOs Operating Guide Reference Input

Stage section for more details. Full FOM performance up to maximum 3.3 Vpp input voltage.
