Working Principle

The SIT9005ACA1H-33EG programmable oscillator is a voltage-controlled device that outputs a frequency that is determined by an electronics setting. The frequency is determined by changing the setting of a resistor, or trimmer capacitor, that is connected to the oscillator. When the setting is changed, the frequency is also changed within its programmed range of 1MHz to 33 MHz. In addition, the frequency is stabilized by a temperature-compensated oscillator (TCO). An internal descriptor memory stores the frequency and other parameters of the oscillator, allowing users to control it without having to reprogram the device.

The SIT9005ACA1H-33EG programmable oscillator has several other features, including low power consumption, a wide supply voltage range and excellent frequency stability. The low power consumption is a product of its high-efficiency design, which is optimized to ensure energy savings. The wide supply voltage range of 1V to 3.3V allows for use in a wide range of applications, including portable devices and those requiring low-voltage operation. The excellent frequency stability is largely due to the integrated temperature-compensated oscillator. This feature ensures that the output signal will stay within the programmed range of frequencies, even with changing operating temperature conditions.
