OscillatorsTC-33.33333MBD-T oscillators are highly accurate, temperature stabilized, quartz crystal oscillators offering superior performance and low-power consumption in small footprint packages. With over 20 years of experience in technology, these oscillators fulfill the design requirements of advanced precision communications and industrial applications.In their most basic form, oscillators are electrical circuits that maintain a constant output frequency or a range of frequencies in the presence of electrical noise, providing an accurate signal source that is stable in a wide range of environmental conditions. The TC-33.33333MBD-T is a temperature-compensated crystal oscillator (TCXO) that employs a temperature-sensing circuit to correct the output frequency of a quartz crystal oscillator in response to changes in temperature. By compensating for temperature, the phase noise of the TC-33.33333MBD-T is significantly reduced over a wide temperature range, making it an ideal choice for industrial and telecommunications applications requiring crystal oscillator stability.Some of the key application fields of TC-33.33333MBD-T oscillators include telecom base stations, medical electronics, SONET/SDH optical networks, and general consumer electronics. These oscillators can be used in wireless systems, such as WCDMA, CDMA2000, and GSM, where precision and low-phase noise are essential. In addition, these oscillators are also used in test equipment, satellite navigation, and automotive applications.The TC-33.33333MBD-T oscillators are available with a frequency range of 3.2 MHz to 33.3333 MHz, and come in a small ceramic package with an operating temperature range of -40°C to +85°C. These oscillators offer excellent frequency stability of ±0.1 PPM, as well as long-term stability of ±2 PPM over 20 years. The operating voltage range of these oscillators is 1.8 V to 3.3 V, with an input frequency pull range of ±30 PPM.The working principle of the TC-33.3333MBD-T oscillator is based on a temperature-compensated oscillator (TCO) circuit. The circuit consists of a quartz crystal resonator, an amplifier, and a temperature sensor. The crystal resonator is the core component of the circuit and the quartz crystal creates a sinusoidal signal frequency that is amplified by the amplifier. The temperature sensor measures the ambient temperature and then provides the corresponding voltage to the TCO circuit in order to fine-tune the oscillation frequency to the desired stability level and accuracy.The TC-33.3333MBD-T oscillator is designed for precision applications requiring reliable frequency stability over a wide range of temperatures. The frequency output of these oscillators is highly stable and accurate due to the temperature compensation circuit, making them perfect for use in industrial, medical, and consumer electronics applications.
