Oscillators

Oscillators are specialized electronic components used to produce digital or analog signals that behave like periodic waves with a particular amplitude and frequency. BF-156.250MCE-T applications belong to a type of oscillator known as a Voltage-Controlled Crystal Oscillator (VCXO). Unlike traditional quartz crystal oscillators, which require a high-frequency clock signal to control and lock frequency and phase, VCXOs use a low-frequency control signal that allows them to operate over a wide range of frequencies with precise frequency regulation and phase control.BB-156.250MCE-T oscillators are widely used in a variety of modern applications such as frequency sources for phased-lock loops (PLLs), frequency synthesizers, high-performance communications systems, test-and-measurement equipment, and frequency-agile transceivers. The oscillator also provides a precise reference frequency for accurate frequency control applications, such as frequency division multiplexing and frequency hopping communications systems.The BF-156.250MCE-T oscillator employs a state-of-the-art high-frequency quartz crystal and an integrated high-performance voltage-controlled oscillator (VCO). The VCO can be tuned with a low-frequency external control voltage. The oscillator is designed with a high-performance Electronic Frequency Control (EFC) loop; this loop enables the oscillator to operate over a wide frequency range, compensated accurately and in accordance with the user’s control signal.The BF-156.250MCE-T also compatible with other high-stability VCXO circuits, including a modified sine wave, a voltage tc wave, and a modified sine wave/triangle combination. The quartz-crystal element of the oscillator is isolated with a photothick layer of gold to ensure stability and accuracy even at high temperatures.The VCXOs used in the BF-156.250MCE-T are renowned for their excellent frequency stability. This frequency stability can be further enhanced with an automatic frequency tuning algorithm implemented at the output of the VCXO. This algorithm allows the oscillator to precisely adjust its frequency in response to a control signal; in this way, the oscillator can maintain precise frequency regulations over a wide range of control voltages.The output frequency of the BF-156.250MCE-T is very low-jitter; this ensures that its output is free from noise and other unwanted interference, resulting in signals with superior accuracy and stability. This makes the oscillator very attractive for use in communications and navigation systems such as GPS, cellular, and military communication networks.In conclusion, the BF-156.250MCE-T is an advanced voltage-controlled crystal oscillator capable of providing precise frequency control, phase control, and low-jitter output signals even at high temperatures. It is widely used in many application fields, including high-performance communication systems and frequency-agile transceivers, owing to its exceptional frequency stability and accuracy.
