Introduction

Programmable oscillators are electronic components that are used to generate clock signals that are used to keep electronic circuits synchronized. They can be used as a timer in a variety of applications including consumer electronics, RFID, automotive, medical, and industrial automation. This article will focus on the SIT8008BCF8-18S programmable oscillator and its application field and working principle.

Application Field

The SIT8008BCF8-18S is a programmable oscillator designed for use in a variety of applications. It is ideal for transmission clock sources and timing control circuits in consumer electronics, RFID, automotive, medical, and industrial automation. The oscillator can also be used for clock synchronization in communication and audio systems, data acquisition and processing, clock switching of digital integrated circuits (ICs), and as a low-power time base for PLL-based clock synthesis.

Working Principle

The SIT8008BCF8-18S programmable oscillator works by allowing the user to input the desired clock frequency and an external clock that it uses as an reference. This data is then used to generate an output clock signal of the desired frequency. The output clock is generated by generating a square wave by switching a binary counter within the oscillator between two logic states. The binary counter is clocked by the external reference clock and each transition of the binary counter will result in one clock cycle of the output clock.The SIT8008BCF8-18S is designed to provide a low power, high accuracy clock generators with a wide range of frequencies and programmability. The device is capable of providing an output frequency range from 0.75 to 25 MHz, which is selectable to an accuracy of ±20 ppm. The oscillator can be easily programmed to a desired frequency using an external voltage-controlled crystal oscillator (VCXO) input. This makes it easy to set the desired clock frequency quickly and accurately. Moreover, the device incorporates an integrated output enable/disable control circuit that allows the output to be easily enabled or disabled by a logic level input. This provides greater flexibility when programming the device and makes it easy to synchronize the oscillator with other components in the system.

Conclusion

In conclusion, the SIT8008BCF8-18S programmable oscillator is a versatile device that is suitable for many applications. It is designed to provide a low power, high accuracy clock generator with a wide range of frequencies and programmability. The device’s integrated output enable/disable control circuit provides added flexibility and control when synchronizing the oscillator with other components in the system.
