Working Principle

The SG-8018CB oscillator operates by generating an oscillating voltage at a certain frequency, shape and amplitude. It does this by utilizing a negative resistance voltage controlled oscillator (VCO) circuit. The VCO circuit is composed of a control voltage source, an inverting amplifier, and an RLC circuit. The control voltage source generates a rectangular waveform. This is inverted by the amplifier and sent to the RLC circuit, which then generates the oscillating output waveform. The amplitude and frequency of the output waveform can be adjusted by changing the amplitude and frequency of the input control voltage.

The SG-8018CB 80.0000M-TJHSA0 oscillator also contains an on-chip temperature compensation circuit which automatically adjusts the frequency over the temperature range from -40℃ to +85℃. This ensures that the oscillator can be used in a wide range of applications and environments without the need for additional thermostatic elements.

The SG-8018CB oscillator is a highly integrated, miniature, low power consuming oscillator. It is suitable for a wide range of applications and has a wide operating temperature range, making it an ideal choice for consumer device applications that require low power, miniature components.
