Programmable oscillators are electronic components used in various electronic circuits. They are used to generate a periodic electronic signal that can be either constant frequency, or variable in frequency or amplitude. The SIT9005ACT1D-30EA is a type of programmable oscillator made by Sitronix. It is an ultra-low phase noise oscillator and is suitable for mobile devices, including cellular phones and PDAs.

Design and Functionality

The SIT9005ACT1D-30EA is a quartz oscillator with a frequency range of 30-150MHz, with a minimum clock frequency of 4kHz. It comes in an industry-standard, hermetically sealed, 8-Pin DIP package for ease of use in portable devices. It is the perfect choice for applications requiring extremely low phase noise and good stability, such as PLL-based systems, radars, and mobile communication applications.

The SIT9005ACT1D-30EA is designed with a 21-bit I²C (Inter-Integrated Circuit) port, allowing users to access a wide range of configuration options and parameter settings. This programmable oscillator supports very low jitter operation and provides the user with a most reliable clock reference.It has programmable frequency stability, balanced and adjustable output power, and can be tuned over a narrow range by an external resistor.

Application Field and Working Principle

The SIT9005ACT1D-30EA is used in a variety of applications, including communication systems, such as Wi-Fi and modems, as well as mobile phones and PDAs. It can also be used in RF systems, such as FM radio receivers and antennas, as well as many other applications.

The working principle of the SIT9005ACT1D-30EA is based on a quartz crystal resonator. The quartz crystal is cut and shaped in such a way that its resonant frequency is equal to the clock frequency of the system. The quartz crystal is placed in a sealed tube and attached to electrodes, which allow an electric current to pass through the quartz crystal. When an alternating current is applied, it causes the crystal to vibrate at its resonant frequency, thus producing a periodic signal. The signal is then amplified and used to drive the system’s clock.

The SIT9005ACT1D-30EA has a very low phase noise level, is highly efficient, and offers a wide range of parameters which can be programmed using its I²C port. Its programmable frequency stability and adjustable output power provide the user with an excellent clock reference, making it the perfect choice for a wide range of applications.
