Programmable Oscillators And The SIT8008BCL3-25E

The SIT8008BCL3-25E is an example of a programmable oscillator, a type of circuit that produces periodic pulses of voltage at fixed intervals. The SIT8008BCL3-25E is a monolithic silicon integrated circuit, made up of both active and passive elements, that utilizes a CMOS process to control the oscillation of a quartz crystal oscillator. Programmable oscillators have been around for a long time, having been used for many applications such as radio communications, wireless networks, and embedded systems. However, the SIT8008BCL3-25E brings with it a variety of features that make it ideal for various applications.

Application Fields Of The SIT8008BCL3-25E

The SIT8008BCL3-25E is an ideal choice for applications such as portable audio devices, GPS receivers, and automotive systems. This is due to the device\'s low power consumption and wide frequency range, making it well suited for low-powered devices. Additionally, the device is highly resilient to shock and vibration due to its monolithic design. Due to the oscillator\'s extremely low jitter of around 3ps (ps stands for picosecond, a unit of time equal to a trillionth of a second), it is also suitable for applications that require highly precise timing. This makes it a great choice for things like cellular and optical communications, medical instruments, and military systems.

Working Principle Of The SIT8008BCL3-25E

The SIT8008BCL3-25E works by utilizing a quartz crystal oscillator as its time source. The oscillator, which produces an electrical signal with a fixed frequency, is controlled by a CMOS process. This process controls the oscillator\'s frequency by adjusting the capacitance between two plates with the help of an external digital signal. The digital signal used to control the oscillator\'s frequency is supplied by an internal digital control logic built into the SIT8008BCL3-25E. This logic is capable of adjusting the oscillator\'s frequency range from 0.2 MHz to 80 MHz by providing a digital code that ranges from 0x00 to 0xFF.

Conclusion

The SIT8008BCL3-25E is an extremely versatile programmable oscillator that can be used in a variety of applications due to its low power consumption, wide frequency range, high shock and vibration resistance, and extremely low jitter. Its ability to adjust the frequency of a quartz crystal oscillator with the help of an external digital code makes it an ideal choice for many application areas.
