FUNCTION
Tuning Inductor Port. Connect an inductor from IND to GND to set VCO center frequency (see Oscillation
Frequency ).
Ground. Connect to the ground plane with a low-inductance path.
Voltage-Control Input for Frequency Tuning. Input voltage range from +0.4V to +2.4V.
High-Impedance Open-Collector Output. An external pull-up resistor or inductor to V CC is required. Output
power is dependent on external load impedance. OUT- is complementary to OUT+.
Supply Voltage Connection. Connect an external bypass capacitor to ground for low noise and low spuri-
ous-output content. See Layout Issues for more details.
High-Impedance Open-Collector Output. An external pull-up resistor or inductor to V CC is required. Output
power is dependent on external load impedance. OUT+ is complementary to OUT-.
