Operating Characteristics Notes:

1. Multiply by VDD /5V for other supply values.

2. The reference level is VTH. The following formula converts dB to mVRMS.

3. Observing pins 13, 14, or 15 (DW/J package) will cause a frequency shift due to additional loading. If tuning center

frequency by observing oscillator, design in a buffer amplifier between pin 15 and probe/calibration point and tune with

no input signal. Otherwise, tune by observing detect output band edges while sweeping input signal. VCO center

frequency is 6(f0) at pin 15 while it is 3(f0) at pins 13 and 14.
