It also comes with embedded diagnostic features which help in guaranteeing reliability and system performance.

The SIT9120AI-2D3-25S166.666600X oscillators offer a wide range of operating frequencies between 1 MHz and 66 kHz. It can also be configured for multiple duty cycles, including a 50/50 square wave and a sine wave. To further refine the design, a range of output logic levels are also supported such as LVTTL, TTL, 3.3V CMOS, LVCMOS and more. In terms of accuracy, the devices feature stability (or performance) of ±50ppm over a wide temperature range of -40°C to +85°C and offer excellent long term stability.

The working principle of the SIT9120AI-2D3-25S166.666600X oscillator involves the use of an oscillator circuit that is tuned to the desired frequency. The circuit consists of an inverting amplifier connected with a tank circuit (made up of an inductor and capacitor) and a feedback resistor. The tank circuit acts as a filter, allowing only a specific frequency to pass while blocking the rest. The output from the tank circuit is then fed back to the input of the amplifier, which is used to amplify the signal. This amplified signal is then fed to the output stage, where it is used to generate an oscillating signal at the desired frequency.

The SIT9120AI-2D3-25S166.666600X oscillator is mainly used portable and embedded electronic devices. It is particularly suitable for applications where size constraints are key such as mobile phones, healthcare sensors and wearables. It is also used in medical, automotive, aerospace and industrial applications where accurate timing signals are needed. The device is designed to provide high performance whilst allowing for significantly reduced system size.
