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 Specifications (@ 25°C and Vs ±15 Vdc) Oscillation Frequency (fo) Range: 100 Hz to 100.0 kHz Tolerance1: ±0.1% Frequency Stability Temperature: 0.02%/°C Supply/Output Amplitude Variation: 0.01%/% Output Characteristics Amplitude Preset: 20V p-p ±0.2 dB Stability vs. Temperature: 0.002 dB/°C Stability vs. Supply Voltage: 0.1 dB/% Drive Capacity Output current @ 20V p-p2: ±5mA pk Output Resistance @ 20V p-p: <10 ohm Distortion Harmonic:3 100Hz to 10.0kHz: 0.1% (-60 dB) 10.1kHz to 50.0kHz: 0.18% (-55 dB) 50.1kHz to 100.0kHz: 0.56% (-45 dB) Noise: 50µVrms DC Power Supply (±Vs) Operating Range: ± 15 Vdc Operating Voltage Range: ± 12 Vdc to ± 18 Vdc Maximum Safe Voltage: ± 18 Vdc Quiescent Current: ± 10 mA typ. ± 12 mA max. Temperature Operating: 0 to + 70°C Storage: -25 to+85°C Notes: Factory adjusted. The output is short circuit protected. Distortion is primarily third harmonic. Specification is for resistive loading. 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.
