Oscillators

The CB3LV-3I-1M0240 is a crystal oscillator designed for use in various critical applications requiring high accuracy. It provides a precision 4 MHz output and has the capability for frequency stabilization over a wide temperature range with an accuracy of ±20 ppm.

An oscillator is a type of circuit or device that produces a regularly varying output voltage or signal. Oscillators are used in a wide variety of applications, such as timing, monitoring, radio frequency (RF) communication, data-acquisition systems, and in portable instrumentation. In general, oscillators generate alternating current (AC) of a specific frequency, which can be varied by changing either the frequency or the duty cycle of the signal.

The CB3LV-3I-1M0240 utilizes a quartz crystal as an active element. The frequency of the crystal is preset and cannot be changed. The crystal is mounted on a printed circuit board and the oscillations are maintained with the help of amplifiers, capacitors, and resistors configured in a closed loop. The output frequency of the crystal is determined by its essential parameters such as its resonance frequency, frequency pull, quality factor, and capacitance.

The CB3LV-3I-1M0240 has a wide range of applications in system timing, synchronization, and instrumentation. It is extensively used in time-keeping for radio applications such as TV broadcast, satellite communication, and cellular networks. It is also suitable as a time-base reference for high-speed data converter systems, clock recovery systems, and sampled data systems.

The working principle of the CB3LV-3I-1M0240 involves the conversion of electrical energy to mechanical energy and vice versa. A voltage is applied to the quartz crystal, which causes it to vibrate at its resonance frequency. The vibrational energy is then transformed into electrical energy and sent as an output signal.

The CB3LV-3I-1M0240 provides a high degree of frequency stability and accuracy of ±20 ppm over a wide temperature range. The oscillator’s operating temperature range is -40°C to +85°C, and it has a very low jitter of <15 ps. It is also immune to high levels of shocks and vibrations, and it can withstand a temperature shock of -55°C to +150°C.

The CB3LV-3I-1M0240 is powered by a low voltage DC supply and it is available in a compact package that supports surface-mount installation. The oscillator is packaged in a hermetically sealed 8-pin DIP form and it offers excellent performance, cost-effectiveness, and reliability.
