SIT9005ACL2G-28EP

Programmable oscillators are components which use the properties of electrical circuits to create precise, regular signals necessary for many systems. The SIT9005ACL2G-28EP is a state-of-the-art unit of this type, designed for use in a variety of applications. It is one of the smallest and most reliable single-piece solutions for regular signal generation in its class.

Features and Components

The SIT9005ACL2G-28EP consists of two main parts, a dual-output oscillator and a frequency programming circuit. This allows for precise, separate control of the device’s rate of oscillation at two separate outputs. The device is capable of accurately controlling either of these outputs in a range 0 - 8MHz, allowing for a degree of fine-tuning which is both precise and easy to control. In addition, the device’s output frequencies may be digitally adjusted in steps of <0.2MHz. The unit also has EEPROM memory to store the settings made via its programming interface, allowing them to be preserved between uses of the device.

The SIT9005ACL2G-28EP also features protection against accidental damage, including reverse current protection and damage due to electrostatic discharges, as well as a low power fail safe mode. In addition, the unit offers a soft start feature, to protect circuitry against inrush current.

Applications

The SIT9005ACL2G-28EP is designed for use in many different areas. It is ideally suited for use in timing and synchronization systems, due to its wide range of flexibly adjustable frequencies and its highly accurate clock outputs. The device is also suitable for use in industrial automation systems, and for motor control and pumps.

The SIT9005ACL2G-28EP is also a great choice for use in medical equipment, due to its robustness and high level of protection against unexpected voltage levels and disturbances. It is perfect for applications such as vital sign monitoring, operating room control systems, and laboratory equipment. Additionally, the device is regularly used in automotive and aerospace applications, as a stable, reliable alternative to analog oscillators.

Working Principle

The SIT9005ACL2G-28EP utilizes a multi-tier architecture to achieve its impressive performance. At its core is a phase-locked loop (PLL) system, with an on-chip voltage-controlled oscillator (VCO). The frequency of the VCO is adjusted dynamically by a digitally controlled capacitor. This capacitance is adjusted according to a stored, adjustable frequency program value, which is read from an external EEPROM or other non-volatile memory device.

The VCO is connected to a synchronization circuit, consisting of a reference oscillator and frequency synthesizer. This circuit is used to adjust the frequency of the VCO dynamically, by comparing it with a reference signal from the reference oscillator. The resulting signal is then output from the device, after being filtered into a stable, low-noise form.

Conclusion

The SIT9005ACL2G-28EP is a powerful, highly reliable programmable oscillator, suitable for use in a wide range of applications. Its features, including dual control of separate outputs, protection against voltage fluctuations and electrostatic discharges, and a sophisticated architecture, make it perfect for use in medical, industrial, aerospace and automotive systems. The SIT9005ACL2G-28EP is sure to become an indispensable device in many applications.
