Oscillators

Oscillators are electrical circuits or devices used in the generation of repetitive signals having some definite or required properties, such as amplitude, frequency, phase, and shape. They are widely used in various applications such as communications systems, broadcasting systems, and industrial system materials.

CB3LV-3C-12M2880 application field and working principle

The CB3LV-3C-12M2880 oscillator is a highly integrated and highly stable voltage controlled oscillator (VCO). It is an ideal solution for applications that require low jitter and low phase noise. The product has excellent performance characteristics and offers cost-effective solutions for various high-performance applications.

The device integrates a low-noise voltage-controlled oscillator (VCO) with a wide frequency range (8 MHz to 2880 MHz) coupled with a reference oscillator. The timing circuit additionally utilizes an adjusted frequency divider to realize a programmable frequency output. It also features an optional integrated loop filter for adjustment or isolation from theVCO core.

CB3LV-3C-12M2880 oscillator is suitable for applications such as radio communication systems, base stations, mobile phones, radar systems, satellite communications, CATV systems, and test equipment. It is designed to operate in a wide temperature range of −30 °C to +85 °C, and it is available in the form of a 9 pin FPV package.

The working principle of the CB3LV-3C-12M2880 is based on the well-known phase-locked loop (PLL) technique. The PLL converts a high frequency signal from the reference oscillator into a low-frequency signal, which is then used as the feedback signal for the VCO. The VCO is then tuned to produce the desired output frequency. The feedback signal is also used to adjust the reference oscillator frequency so that it remains in lock with the VCO frequency.

The adjustable divider, reference clock, and loop filter are also incorporated into the design to ensure that the output frequency remains within a narrow band. The loop filter is used to reduce noise or jitter generated by the reference oscillator, while the adjustable divider is used to set the frequency of the output signal. Adjustment of the frequency divider also provides immunity against external disturbances, such as temperature drift, power supply fluctuations, and other extraneous noise sources.

The primary features of the CB3LV-3C-12M2880 oscillator include high stability and low jitter, adjustable frequency, wide temperature range, programmable amplitude control, wide input voltage range, and low power consumption. The device offers excellent performance characteristics and is an ideal solution for applications requiring low jitter and low phase noise.
