Programmable Oscillators, like SIT9005ACT1G-25EC, are designed to provide a card, no external trimming and a wide variety of electrical characteristics and performance parameters.

Programmable oscillators utilize a microprocessor that provides users with flexible timing solutions. By utilizing programmable oscillators, one can tailor the oscillation frequency to meet design requirements when other standard oscillators may not be suitable. These oscillators are also useful in applications where temperature stability is required or where a range of different oscillation frequencies are needed from one IC.

The SIT9005ACT1G-25EC, is a highly programmable, low power and long-term Crystal Oscillator with four programmable parameters and is the latest addition to the SIT9005 family. This oscillator has many useful practical applications. It can be used in the industrial, medical and automotive applications, among others.

The SIT9005ACT1G-25EC is a low power, double pole crystal oscillator that has a center frequency accuracy of +/-20ppm, phase jitter of 0.35ps, and high frequency stability. It has a high output drive strength of up to 50mA. The SIT9005ACT1G-25EC can be operated with a supply voltage range between 1.8V to 5.5V and also provides a low operating temperature range from -40 to +115°C. Furthermore, it has an internal temperature sensor to allow for quick temperature corrections and improved stability.

The SIT9005ACT1G-25EC features on-chip programmable features and options, helping to identify multiple parts and to conveniently configure, configure and maintain crystal oscillators. Through the programmable options and by programmable parameters available, the control of oscillator frequency, phase, pull-ability and temperature insulation is also possible. The other important feature of the SIT9005ACT1G-25EC is its integral Charge Pump output, allowing it to drive a wide variety of pullable XTALs, including the high-Q family of XTALs.

The working principle of the SIT9005ACT1G-25EC is based on the dual-mode operation of a crystal oscillator. A crystal oscillator consists of a crystal, which is the resonator, and an amplifying and buffer circuit. The crystal oscillator also consists of a control circuit, which supplies bias to the amplifier/buffer circuit, determines the self Operating frequency, and sets the amplitude of the oscillation. The control circuit is responsible for controlling the frequency of the oscillator. It includes a microprocessor that is constantly adjusting the internal signals according to the programmed parameters and conditions. In addition, the programmable parameters allow users to set the oscillator\'s output power, frequency, phase and pull-ability.
