Programmable oscillators are widely used in many electronic applications like medical technology and communication systems. Their ultimate goal is to be adjustable and controllable to meet the desired frequency and output requirements. SIT9005ACR1G-18DL, one of the most widely used programmable oscillators is a prime example ofthese oscillators. This article highlights the application fields of SIT9005ACR1G-18DL and its working principle.

The SIT9005ACR1G-18DL is a versatile clock generator designed for a wide range of common frequency output ranges and output formats. It is designed to optimize efficiency when driving SoC, ASIC or FPGA clocking systems. It can be used in network synchronization, precision clocking applications across enterprise and short-haul networks, automated test systems, printed circuit boards, digital signal processors, communications, phase-locked loop systems, telecom, automotive, aerospace and a wide range of general-purpose applications. It has excellent jitter performance, frequency accuracy and is available in assorted temperatures and supply voltages.

The working principle of SIT9005ACR1G-18DL is based on its two main components, frequency oscillator and digital input. The frequency oscillator is of the RC type controlled by an external capacitor. When the oscillator frequency varies, a change in the charging or discharging time of the external capacitor is seen. This change is measured in terms of DAC voltage applied to the terminals of the frequency oscillator. The digital input allows the output frequency to be digitally programmed with the correct code sequence and the DAC voltage is then adjusted to the desired frequency. The result is a constant, adjustable and controllable frequency output over a range of frequencies.

Apart from being used in applications like telecom, automotive, aerospace and etc., the versatility of SIT9005ACR1G-18DL is extended to digital logic and modulated communications systems. It is ideal for controlling SMPTE (Society of Motion Picture and Television Engineers) based processing equipment and timing functions. Its stable and low-jitter performance design allows for easy synchronisation of HDTV (High Definition Television) and SDTV (Standard Definition Television) systems. Its low-power consumption design also makes it attractive to be used in display and high-definition imaging devices.

Lastly, the SIT9005ACR1G-18DL is an extremely powerful programmable oscillator that is capable of providing a wide range of output frequencies, levels and formats. Its wide range of applications in telecommunications, automotive and airborne applications, medical technology and general purpose applications, make it one of the most sought after programmable oscillators. Its high-accuracy, low jitter characteristics and easy programmability are the key factors that differentiate this oscillator from the competition. The wide range of frequency selections, output formats and integrated temperature compensation, ensure that users get the best performance from this oscillator.
