Programmable oscillators are components used to generate an output signal of a certain frequency or range of frequencies, which can then be incorporated into many types of electronic circuits. These components are particularly useful in applications requiring a high degree of precision and accuracy in controlling frequency, such as those found in the telecommunication industry, military, and aerospace systems. The SIT9005ACL1H-30DK is an example of a programmable oscillator, and this article will discuss its application field and working principle.

The SIT9005ACL1H-30DK is a high precision crystal oscillator with a Frequency range of 27.8 kHz - 70.0 kHz. It is a 3.3 Volt / 5.0 Volt LVCMOS (Low-Voltage CMOS) programmable oscillator, made with a quartz crystal wafer design and encapsulated in a 4-pin, 14-pin J-lead package. This oscillator is well-suited for many mission-critical applications where precision frequency control is needed. Its small size and energy-saving design also make it a desirable choice for portable electronic devices such as cell phones and other mobile devices.

The SIT9005ACL1H-30DK features a wide range of selectable output frequencies and features an adjustable duty cycle for additional control of the output waveform. The frequency range can be configured in two ways: either by connecting two separated external components (as a low-cost chip or as a separate or OEM-fitted external circuit) or by using internal resister network digitally. The duty cycle of the output signal is adjustable between 50% and 90% by means of the internal binary control register. The accuracy of the output frequency is ±1% over temperature with a maximum tolerance of ±50ppm.

The SIT9005ACL1H-30DK is designed for applications requiring a high degree of precision in frequency control and for long term stability. It offers reliable performance over a wide temperature range: from -40°C to +85°C. This device is well-suited for use in a wide range of applications, from telecom to space-based systems. It has been especially well-received in the telecom industry, where it has been used to provide precise timing control in base station systems, VoIP equipment, mobile communications, and GPS applications.

The working principle of the SIT9005ACL1H-30DK is based on a quartz crystal oscillator design. A quartz crystal mechanically vibrates based on an electric field applied across it. As the electric field increases, the quartz crystal vibrates at a higher frequency; and as the field decreases, the vibrating frequency also decreases. The frequency at which the crystal vibrates is determined by the frequency at which the electrical field is applied across the quartz crystal.

The SIT9005ACL1H-30DK utilizes a feedback circuit to maintain the frequency of the output signal at a desired point. The electrical field is applied to the quartz crystal by a closed loop oscillator circuit, which has two components: the amplifier and the feedback network. The amplifier produces a small output signal from the reference input signal, which is then amplified and sent to the crystal. The quartz crystal then produces an oscillations corresponding to the frequency of the voltage. The output signal of the crystal is then amplified and sent to the feedback network, which filters the signal and provides it with a constant-level boost. The feedback circuit then produces the output signal at the desired frequency.
