Band Gap voltage filter connection.
Loop Filter component connection.
Connection for loop bandwidth control resistor.
POWER pin for the VCO. Connect to a 1.2V±5% analog supply
followed by a RC filter (see 5.3 Typical Application Circuit). A 105Ω
1% resistor must be used in the RC filter circuit. VCO_VDD is
nominally 0.7V.
