Oscillators are widely used in many electronic applications, as they are responsible for creating regular electrical signals. The CMX309FLC12.288M-UT oscillator is one of the most popular oscillators on the market, due to its wide range of applications and reliable performance.

The CMX309FLC12.288M-UT is a miniature temperature-compensated CMOS oscillator, designed to produce very low jitter in the range of 0.4ps RMS over 125MHz. Its output holds a frequency accuracy of ±25ppm, and it has low power consumption of 1.2mA at 3.3V.

The CMX309FLC12.288M-UT is capable of operating in temperatures ranging from -40°C to +85°C, which makes it well-suited for use in extended temperature range applications. It is used in a wide variety of telecommunications, industrial, and consumer applications and can be used in both CMOS and TTL logic systems. It also supports both crystal and ceramic packaging formats.

The CMX309FLC12.288M-UT oscillator utilizes a number of techniques to provide excellent jitter performance, frequency accuracy, and power efficiency. It relies on a low-distortion stage that helps to reduce clock jitter, an on-chip temperature-compensated crystal oscillator (TCXO) that increases frequency accuracy, and an on-chip switching regulator circuit that improves power efficiency.

The TCXO is designed to adjust the frequency of the oscillator depending on the temperature, and is the main contributor to the accuracy of the oscillator. The TCXO is controlled by an on-chip voltage regulator, which with the use of an external resistor adjusts the voltage of the output signal. This voltage is then used to adjust the frequency of the oscillator, compensating for any changes in the ambient temperature.

The output signal is then filtered to remove any unwanted noise and jitter, ensuring that the signal is as clean and accurate as possible. The CMX309FLC12.288M-UT also features a built-in PLL circuit which allows it to be more easily synchronized with an external clock signal.

The CMX309FLC12.288M-UT oscillator is an incredibly versatile oscillator that can be used in a variety of applications. It is well-suited for telecom and industrial applications, due to its wide operating temperature range and frequency accuracy. It is also ideal for consumer applications, as it requires very low power and produces very low jitter.
