VCO Bypass. Bypass with a 0.1μF capacitor to GND.
Oscillator Frequency Tuning Voltage Input. High-impedance input with a voltage input range of +0.4V
(low frequency) to +2.4V (high frequency).
Ground Connection for Oscillator and Biasing. Requires a low-inductance connection to the circuit
board ground plane.
Shutdown Logic Input. A high-impedance input logic-level low disables the device and reduces supply
current to less than 1.0μA. A logic-level high enables the device.
Bias and Oscillator DC Supply Voltage Connection. Bypass separately from pin 6 with a 220pF
capacitor to GND for low noise and low spurious content performance from the oscillator.
Output Buffer DC Supply Voltage Connection. Bypass separately from pin 5 with a 220pF capacitor to
GND for best high frequency performance.
Buffered Oscillator Output. Incorporates an internal DC-blocking capacitor. OUT is internally matched
to 50 .
Ground Connection for Output Buffer. Requires a low-inductance connection to the circuit board ground
plane.
