Introduction

Programmable Oscillators are semiconductor devices that utilize electrical current to generate a predetermined periodic signal, referred to as a clock signal, used for data transfer in digital and communication applications. The output frequency of the clock signal can be determined by the design characteristics of the device or externally applied voltages. SIT9005ACB1G-25SP is an example of such a device. This document will discuss the application fields and working principle of the SIT9005ACB1G-25SP.

Application Fields of the SIT9005ACB1G-25SP

The SIT9005ACB1G-25SP is a programmable oscillator device suitable for applications where precise and stable clock signals are required for data transfer. These applications include consumer, industrial, medical, or automotive electronics. It can provide reliable signals for a broad range of systems, such as control loops, synchronous communications, sensors, or audio/video equipment.The SIT9005ACB1G-25SP is also suitable for distributed system clock applications. It has a unique on-chip technology known as Dual Clock Output (DCO), which provides the option to configure two independent clock outputs with the same frequency or different frequencies. This feature makes the device suitable for telecommunications, broadcast, and multimedia applications.

Features of the SIT9005ACB1G-25SP

The SIT9005ACB1G-25SP is a highly configurable device, allowing the user to adjust the output frequency within a wide range. It has the ability to produce a wide range of frequencies up to 200 MHz with a jitter of less than 500 ps. The SIT9005ACB1G-25SP also features a ±50 ppm stability over temperature, and an integrated voltage-controlled oscillator (VCO) for easy clock frequency tuning.The SIT9005ACB1G-25SP also has robust power characteristics, making it suitable for battery-operated devices. It has a power consumption of only 8 mW, making it an ideal choice for applications that require low power consumption.

Working Principle of the SIT9005ACB1G-25SP

The SIT9005ACB1G-25SP is a programmable oscillator device that produces stable clock signals for data transfer. It consists of an oscillator circuit made up of a resonator, such as a quartz crystal, and a voltage-controlled oscillator (VCO).The resonator is used to stabilize the generated clock frequency. Its frequency is determined by the crystal\'s characteristics, such as its cut and type. The VCO is used to modulate the frequency of the generated signal. The VCO frequency is determined by the voltage applied to it, which can be externally adjusted.In a stable frequency application, the SIT9005ACB1G-25SP will use the resonator to stabilize the frequency and the VCO to coarse-tune the frequency. In an application where the frequency needs to be adjusted remotely, the SIT9005ACB1G-25SP will use the VCO to both stabilize and adjust the frequency.

Conclusion

The SIT9005ACB1G-25SP is an example of a programmable oscillator suitable for a broad range of applications. It has features such as a wide range of frequencies up to 200 MHz with a jitter of less than 500 ps, low power consumption, and dual-clock outputs. The device also has a sophisticated working principle involving a resonator and a voltage-controlled oscillator (VCO) to generate stable and precise clock signals for data transfer in digital and communication applications.
