SIT8009BCF21-30N

Programmable oscillators come in various formats, sizes and features and provide electronic circuit designers with unprecedented flexibility to control the frequency and amplitude of their oscillators with the help of digital control systems. The SIT8009BCF21-30N is one such programmable oscillator that can be used to generate clock signals, offering a wide range of applications.

This oscillator consists of an integrated circuit containing both a frequency-dividing circuit and a reference frequency circuit. An external layer of electronics, consisting of resistors and capacitors, is used to control the signal frequency, while the reference frequency is generated within the oscillator itself. The signal is then divided into a number of cycles using the frequency-dividing circuit, resulting in a periodic signal.

The SIT8009BCF21-30N offers a programmable frequency range between 0 and 150MHz, as well as power supply range between 3V and 7V. This makes it ideal for use in a wide variety of applications, including frequency synthesisers, time bases, and data communications. It also has short-term stability when powered from an external source, meaning it can maintain accuracy even when the power source is turned off or changed. The oscillator is also dual-input-capable, meaning it can be used with both LVCMOS and CMOS logic systems.

The most important feature of the SIT8009BCF21-30N is its ability to be programmed. This is done via a series of digital control registers, which are used to specify the frequency, phase shift, duty cycle, and current consumption. This provides the user with the ability to easily adjust the signal generation settings to suit their particular application. Furthermore, the oscillator can be reprogrammed to different settings as needed, providing added flexibility over fixed frequency oscillators.

In addition to its programmability, the SIT8009BCF21-30N also offers a high level of accuracy and stability. It achieves an accuracy of ±1.5 ppm over the temperature range of -40°C to 85°C, and offers a long-term stability of 2 ppm/year. This ensures that the oscillator can provide a consistent and reliable signal throughout its lifetime.

The SIT8009BCF21-30N programmable oscillator is an ideal choice for applications ranging from communications and test equipment to automotive and industrial electronics. With its programmability, accuracy, and stability, it provides a versatile and cost-effective solution for a wide range of applications.
