Description

The D45Q Oscillators are fixed frequency sine wave oscillators that deliver two high purity sinusoidal outputs that are 90 degrees out of phase. These fully finished devices can be user specified to operate to any frequency between 100 Hz and 100.0 kHz.

Each D45Q model includes sine and cosine 7.07 volt rms (±0.2 dB) outputs with total harmonic distortion of less than -45 to -60 dB depending on frequency. The phase between the sine and cosine outputs is 90.00 degrees ±0.15 to ±0.30 degrees depending on frequency.

Features/Benefits:

  • Stable high purity sinewave output.
  • Compact 1.8"L x 0.8"W x 0.3"H minimizes board space requirements.
  • Plug-in ready-to-use, reducing engineering design and manufacturing cycle time.
 

Applications

  • Reference oscillator
  • Airborne equipment
  • Mobile equipment
  • Test Apparatus
  • Telemetry Systems
  • Distortion Testing

Notes:

  1. Factory adjusted.
  2. The output is short circuit protected.
  3. Distortion is primarily third harmonic. Specification is for resistive loading.
  4. How to Specify Oscillation Frequency:
    Oscillation frequencies are specified by attaching a three-digit frequency designator to the basic model number. Oscillation frequencies can range from 100 Hz to 100.0 kHz.
