Oscillators are devices that generate an output signal of a specific frequency. BT-156.250MBC-T is one such oscillator. It is a temperature-controlled crystal oscillator (TCXO) that offers higher stability and less susceptibility to environmental variations for applications in various fields.

The BT-156.250MBC-T oscillator is designed to be used in the 156.25 MHz frequency range. The primary application of the oscillator is in radio-frequency (RF) communications. The oscillator is ideal for use in wireless communications systems, such as digital cellular phones, GPS receivers, satellite receivers, and mobile radio systems. It is also suitable for use in base stations, point-to-point communications systems, and direct-sequence spread-spectrum systems.

The BT-156.250MBC-T oscillator is designed to offer exceptional performance over environmental variations in temperature. The oscillator features a tight frequency tolerance of ±0.5 ppm over a temperature range of –10°C to +60°C. This ensures very stable performance over a wide range of temperatures.

The oscillator also features excellent phase noise performance, with a noise level of –145 dBc/Hz at 10 kHz offset and –155 dBc/Hz at 100 kHz offset. The oscillator’s low noise level ensures that it can be used in applications where low noise is essential, such as radio and RF communications systems.

The BT-156.250MBC-T oscillator also features a low current consumption of 6 mA (typical). This makes it ideal for use in portable devices, where power consumption is a major concern. The oscillator is also available in a variety of package types, making it suitable for a range of applications.

The BT-156.250MBC-T oscillator operates on a fundamental principle known as the “piezoelectric effect.” This is a phenomenon where an electrical charge is generated in response to a mechanical stress applied to a certain type of material. In the case of the BT-156.250MBC-T oscillator, the piezoelectric material is a quartz crystal, which is placed in a feedback loop in order to generate a specific frequency.

The core of the oscillator is a quartz crystal which has electrodes attached to it. When the crystal is subjected to an alternating voltage, it vibrates, producing a periodic mechanical strain which generates a minute electrical charge. This charge is then amplified and then returned to the crystal, where it causes the same strain to be applied in reversed direction. This produces a periodic change in the electrical resistance of the crystal, resulting in an oscillating signal at the desired output frequency.

The frequency of the generated signal depends on the dimensions of the crystal and the applied voltage. The BT-156.250MBC-T oscillator is designed to work at a specific frequency of 156.250 MHz. By adjusting the voltage applied to the oscillator, the frequency can be adjusted within a small range.

The BT-156.250MBC-T oscillator is a temperature-controlled device, meaning that the frequency of the output signal is automatically adjusted as the temperature changes. This ensures that the oscillator can maintain the desired output frequency over a wide temperature range.

In summary, the BT-156.250MBC-T is a temperature-controlled crystal oscillator that is designed to be used in the 156.250 MHz frequency range. It features excellent frequency stability and phase noise performance, as well as low current consumption and a wide range of package types. Its output frequency can be adjusted by a small amount, although the frequency is automatically adjusted to compensate for temperature variations. Thus, it is a highly reliable and versatile oscillator that is suitable for many different applications.
