Working Principle of SIT9005ACF1H-30DK

The working principle of SIT9005ACF1H-30DK follows a combination of crystal oscillator and digital ASIC technology. The crystal oscillator inside this oscillator family is designed for improved linearity and accuracy. It also offers superior long-term stability and low-noise performance. The digital ASIC oscillator consists of an integrated FET switch, a voltage regulator and a temperature stable oscillator circuit. The temperature stable oscillator circuit is divided into three major parts – a low-pass filter, a voltage-controlled oscillator (VCO) and a frequency divider. The low-pass filter removes unwanted noise and provides the signal with a nearly constant amplitude-frequency (AF) curve. The VCO then takes the filtered waveform and generates an AC signal of specific frequency. This signal is then divided down to a lower frequency range in the frequency divider.
