DSC1001BI2-016.9344T Application Field and Working Principle

The DSC1001BI2-016.9344T is a quartz-based temperature compensated oscillator (TCXO) designed for a wide variety of applications. This model of TCXO is capable of operating in extreme temperatures, with a typical drift of only 0.03 ppm/°C over the operating temperature range of -40°C to +85°C. This low power tracking oscillator is offered in a 10.0 x 7.5 x 2.5 mm hermetically sealed, ceramic SMD package. This TCXO features a low phase noise of -125 dBc/Hz at 100 kHz offset, low current consumption of 1.0mA max at 2.8Vdc and a wide frequency range of 16.80 to 16.9344 MHz.

The key to the DSC1001BI2-016.9344T\'s performance is the reliable quartz crystal used in its construction. In a typical quartz crystal resonator system, an oscillation circuit is created once an adequate load capacitance is connected to the crystal and the crystal is driven with a signal. The signal is then fed back to the crystal, creating an inductive feedback loop and causing it to oscillate at its resonant frequency. This resonant frequency is determined by the quartz crystal\'s structure and the mass of the electrodes connected to it.

The oscillator circuit creates a sinusoidal output waveform, which is regulated by an electronic temperature compensation circuit. This temperature compensation is necessary to maintain the oscillator\'s accuracy in various environmental conditions. The output of the temperature compensation circuit is fed into the oscillator circuit, which adjusts the crystal\'s frequency according to the temperature. This adjustment is necessary to keep the oscillator\'s output frequency constant.

The DSC1001BI2-016.9344T is designed for a wide variety of applications, including cell phones, wireless communication systems, personal digital assistants (PDAs), and consumer electronic products. The low current consumption and wide temperature range make it ideal for use in portable devices where energy conservation is a major concern. Additionally, its low phase noise and wide frequency range make it suitable for use in high-precision devices, such as satellite receivers and GPS systems.

In summary, the DSC1001BI2-016.9344T is an excellent TCXO oscillator designed for a wide range of applications. Its low current consumption, wide frequency range, low phase noise, and precision temperature compensation make it suitable for a variety of applications, from cell phones to satellite receivers.
