SIT9005ACT1H-XXNE is a programmable oscillator which provides frequency control for various applications. It offers a wide frequency range and a number of convenient features, making it suitable for a multitude of applications. This article provides an overview of the SIT9005ACT1H-XXNE programmable oscillator, including its field of application, its working principles, and other features.

Application

The SIT9005ACT1H-XXNE is a general-purpose programmable oscillator that can be used in numerous applications in industrial and consumer environments. It is especially suitable for repetitive timing applications such as automotive electronics, consumer electronics, instrumentation, medical, telecommunications and measuring & control apparatuses. It is also suitable for various clock signal generation for processors, cell phones and other electronic appliances.

The SIT9005ACT1H-XXNE provides precise low-jitter clock signals from a wide range of frequency outputs from 1 kHz to 50 MHz. This frequency range makes the device suitable for different time-measuring, frequency monitoring and synchronization requirements. Furthermore, it is capable of handling a wide range of supply voltages, allowing it to be used in extreme environmental conditions such as low temperature and high air pressure.

Working Principle

The working principle of the SIT9005ACT1H-XXNE is based on the well-known quartz crystal oscillators which generate signals at precise frequency. The SIT9005ACT1H-XXNE consists of a temperature-compensated oscillator (TCXO) and an adjustable frequency generator (AFG) built into a SC-70 package. The TCXO is used to generate a stable frequency. The built-in AFG allows the frequency of the TCXO to be expanded to cover a wide range of frequencies. This makes the SIT9005ACT1H-XXNE suitable for applications which require precise timing signals.

The SIT9005ACT1H-XXNE is equipped with an internal 10-bit digital-to-analog converter (DAC) which controls the frequency of the TCXO. The DAC is programmed by an external digital control line through an I2C or SPI interface. This digital interface allows the frequency of the oscillator to be adjusted over a wide range while still providing a high degree of accuracy. Furthermore, the device provides a selectable oscillator start-up time to allow for reduced power consumption and longer device lifetimes.

Additional Features

The SIT9005ACT1H-XXNE also offers several additional features which make it a highly attractive product for several applications. For example, the device offers variations in the package type, allowing it to be used in different applications with different requirements for physical size, power consumption and reliability. Additionally, the device is capable of providing a wide range of frequency output levels, from 0.8 LVTTL to 3.3V LVTTL. Finally, the device is equipped with an optional “AutoSleep” mode which reduces power consumption when the frequency of the output signal is not required. This feature is especially useful in low-power and battery-powered devices.

Conclusion

The SIT9005ACT1H-XXNE is a highly valuable programmable oscillator suitable for a wide variety of applications. Its wide range of frequency outputs, digital interface, and optional AutoSleep mode make it attractive for a wide range of industrial and consumer applications. Furthermore, its package type variations and wide range of frequency output levels make it suitable for use in even the most extreme environmental conditions.
