Oscillators are electric devices that generate an alternating current signal controlled by a fixed frequency or controlled by external influences. In its simplest form, an oscillator is used to generate sinusoidal, square wave or triangle wave forms, as well as multivibrators, which are devices that produce multiple wave forms from a single input. The SIT9120AC-2C1-33E125.000000T is an active quartz oscillator designed for high performance applications where low jitter, low power consumption and low cost are key factors in component selection.

The SIT9120AC-2C1-33E125.000000T features an embedded 32.768 kHz crystal and a voltage-controlled oscillator (VCO) that provides an adjustable output frequency range of 0.256 kHz to 31.25 kHz. The device is capable of delivering a minimum output of 20 mV (0.5 Vpp) with accuracy and long-term stability of 0.002% per grams. This high performance allows the device to be used in a variety of applications such as automotive, GPS, industrial, telecommunications and medical applications.

The SIT9120AC-2C1-33E125.000000T has a very low power consumption of just 2.5 mW and can operate over a wide temperature range of -40°C to +105°C. The device’s compact size (4mm x 4mm x 1.6mm) makes it suitable for use in space constrained applications and it is highly resistant to EMI and ESD due to its EMC-enabled hermetic package.

The SIT9120AC-2C1-33E125.000000T has several features that enable it to produce high resolution clock signals. The device is equipped with a quartz tuning voltage control loop (VCC) that allows precise frequency control, and a fine-tuning voltage control loop (FTVLC) to provide frequency stability over the operating temperature range. The device also includes a built-in Stress Signal Generator (SSG) to reduce transient jitter, and phase-locked loop circuitry (PLL) to synchronize the output signal with an external reference signal.

The working principle of the SIT9120AC-2C1-33E125.000000T is based on the fact that quartz crystals have the property of vibrating at a set frequency when a small electric signal is applied across them. This vibration frequency is determined by the mass and shape of the quartz crystal and can be used to generate a precision oscillating signal. In the SIT9120AC-2C1-33E125.000000T the crystal is incorporated in a voltage-controlled oscillator (VCO) circuit. The output frequency of the oscillator is controlled by the VCO control voltage, which is a voltage level that can be adjusted to fine-tune the frequency of the signal. This allows for accurate and precise clock signals to be generated over a wide range of frequencies.

The SIT9120AC-2C1-33E125.000000T is an active quartz oscillator designed for high precision clock applications. Its low output jitter, low power consumption, wide operating temperature range and EMC protected hermetic package make it well suited for many applications, including automotive, GPS, industrial, telecommunications, and medical. The quartz tuning voltage control loop (VCC) and fine-tuning voltage control loop (FTVLC) enable precise frequency control, while the built-in stress signal generator and phase-locked loop circuitry facilitate synchronization of the output signal with an external reference signal.
