SIT1602AC-22-33E-66.666600D Oscillators: Application Field and Working Principle Oscillators are electrical circuits that produce a repeating signal without the need of any input other than power. The power is occasionally referred to as the clock signal and the timed signal can be in the form of an oscillation, ranging from basic sinusoidal waves to very complex square waves and saw-tooth waveforms. Oscillators are driven by amplifiers, mixers, amplifiers, and other types of power circuits. The most well-known oscillators are oscillators of the SIT1602AC-22-33E-66.666600D series. SIT1602AC-22-33E-66.666600D oscillators are dual-mode oscillators that utilize a patented dual-mode design to create a low-voltage, low-power oscillator. This oscillator produces a stable sinusoidal waveform with a duty cycle of 65 to 75%. The dual-mode design allows for either autonomous oscillation or on-demand mode, depending on the application.When used in autonomous mode, the SIT1602AC-22-33E-66.666600D oscillator can generate an adjustable frequency up to 700KHz. This oscillator is ideal for applications where a specific frequency, or range of frequencies, must be maintained. The oscillator requires a five to seven Volt DC power supply and an external load resistor. The oscillation frequency is adjustable by inserting a variable resistor, or potentiometer, into the external resistor. In on-demand mode, the SIT1602AC-22-33E-66.666600D oscillator is driven by a low-voltage external logic input. When the logic input is activated, the oscillator immediately produces a frequency equal to that set by the external potentiometer. The logic input also enables the oscillator to change frequency in response to changes in the external conditions, making it highly flexible and reliable.The SIT1602AC-22-33E-66.666600D oscillators are suitable for use in a wide range of applications. These include frequency control in test & measurement instruments, PWM, triggering, and advanced AC power management. The oscillators are also used in automotive applications for powertrain control, as well as in white goods, robotics, surveillance systems, and medical applications.The SIT1602AC-22-33E-66.666600D oscillators have a wide temperature range of -0°C to +75°C and are highly reliable, with an MTBF of 40,000 hours. They also come with an on-chip watchdog timer to protect against system lock-up. The oscillators feature a true zero-speed operation, low-jitter operation, and a digitally adjustable reference frequency. Additionally, they are RoHS compliant and are rated for up to 10mA of output current.In conclusion, the SIT1602AC-22-33E-66.666600D oscillator is an efficient, reliable, and highly versatile oscillator that can be used in a wide variety of applications. It is capable of autonomous operation and can be used for precise frequency control due to its adjustable external resistor feature.
