Programmable oscillators are electronic components which provide variable frequency outputs when voltage is applied. The SIT9002AC-38H18SO is one such example. It is a surface mounted device designed to offer multiple output periods and variable frequency outputs. This article discusses the application fields and working principles of the SIT9002AC-38H18SO.

Application Field of SIT9002AC-38H18SO

The SIT9002AC-38H18SO is primarily used in Consumer Electronics, Automotive, Industrial, Defence and Communications. It uses a high-performance PWM-Timer IC and can provide outputs at high switching frequencies of up to 38MHz. Because of its small size, it can be used in compact design applications, making it well suited for a range of applications in the Automotive, Industrial, and Defence sectors.

Its main use is in providing variable frequency outputs for clock timing systems. It can provide clock signals to highly integrated ports and can also be used in memory systems. The SIT9002AC-38H18SO is also very useful for its low-power consumption and long-term stability, making it suitable for applications requiring long-term reliability.

Working Principle of SIT9002AC-38H18SO

The SIT9002AC-38H18SO operates using a 4-pin TO-18 metal-can configuration. It is designed to have a low ripple current draw of 0.7~0.9μA. By using the clock input, it can handle input frequencies up to 38MHz. The device is also equipped with protection circuits, which prevent destruction of internal circuits by unnecessarily large input currents.

At the core of the SIT9002AC-38H18SO is the TS91566-2BSI, a PWM timer integrated circuit. This circuit continuously switches the output between high and low states at variable frequencies. The frequency is set by the ratio of the two externally-connected oscillators. By adjusting the ratio, an accurate and consistent output can be obtained over a wide frequency range.

The SIT9002AC-38H18SO also has a wide operating temperature range of -40°C to +85°C, so it can be used in a variety of environments. Additionally, the device is provided in a compact size (only 2.2mm x 3mm) and low weight, allowing it to be used in space-constrained applications. To complete the package, the SIT9002AC-38H18SO also offers an over-voltage protection circuit, which helps protect the device against power surges.

Conclusion

The SIT9002AC-38H18SO is a versatile programmable oscillator designed for use in multiple applications. Its ability to provide variable frequency outputs and withstand operating temperatures allow it to be used in a variety of environments. Furthermore, with its low power consumption, over-voltage protection circuit, and small size, it can be used reliably in applications where space is a concern.
