An oscillator can be generically defined as any device which produces an alternating signal or oscillation, typically in the form of voltage or current, which can then be used as part of electronic circuits to perform various operations. As such, oscillators are very necessary components in modern day electronics, providing the driving signal in various circuits ranging from communication systems, audio signals, high performance computing, and many more scenarios. Among oscillators, SIT3807AC-D3-33SE-11.289600Y is a type of voltage controlled crystal oscillator (VCXO) manufactured by Sitronix Technology Corporation, designed to provide excellent short term stability, low phase noise linear control, and low jitter characteristics for its frequency output.Application fieldsSIT3807AC-D3-33SE-11.289600Y oscillators, as a VCXO, best finds its application in ultra-precision frequency control or frequency synthesis applications. In current age, the VCXO offers a suitable option for situations when something other than a regular, simple crystal oscillator (XO) is needed - something that offers more precise control of frequency without costing as much as a frequency synthesizer would do. The SIT3807AC-D3-33SE-11.289600Y is a premium choice to execute this purpose, with its product specifications offering excellent control of output frequency - good enough to perform precision frequency control and synthesis.VCXOs, in general, are best used to establish the fundamentals of a frequency for Radio Frequency (RF) applications such as transceivers, base transmitters and receivers, airborne and wireless communication systems, and other similar applications. The SIT3807AC-D3-33SE-11.289600Y VCXO is also used by a lot of WLAN Wi Fi modem manufactures which include Wi Fi Direct, GoldTel, and Moin. Even more, the extended temperature of the SIT3807AC-D3-33SE-11.289600Y makes it suitable for applications and operation outside of a traditional, temperature controlled environment, and makes it especially reliable in automotive, aviation and other outdoors related applications.Working Principle and Product SpecificationsThe SIT3807AC-D3-33SE-11.289600Y is a voltage controlled quartz oscillator, which means it operates using standard quartz crystal vibrators to produce a clock signal. The standard quartz crystal vibrator is placed at the heart of the oscillator, with external circuitry surrounding it to modify the frequency of the generated signal by using voltage control. The main components of the VCXO are two capacitors and two resistors, with the quartz crystal vibrator at the core of the circuit. As shown in the diagram below, the signal to be generated is superimposed on top of a d.c. control voltage (Vc) applied to the VCXO, resulting in an oscillating output signal at the output frequency fo .In addition, the SIT3807AC-D3-33SE-11.289600Y has the following specifications: - Power supply voltage : 3.3V ± 10% - Output Frequency Range : 11.289600MHz - Frequency Tolerance : ± 25ppm- Storage Temperature : -55 to +125°C - Operating Temperature : -40 to + 85°C - Supply Current : 10mA Max - Control Voltage : 0.2Vp-p to 3.6V p-p - Load : 10pF Max. ConclusionThe SIT3807AC-D3-33SE-11.289600Y is a versatile Voltage Control Crystal Oscillator (VCXO) with great features and product specifications, suitable for use in a wide range of frequency control and frequency synthesis applications. Its simple and low cost structure makes it an appropriate choice for a number of situations, and its range of temperature capabilities in particular makes it reliable for use in automotive, aviation and outdoors related applications.
