CVCO55CL-1073-1086 Crystals, Oscillators, Resonators

Voltage Controlled Oscillators (VCOs) are electronic oscillator circuits whose average output frequency can be varied by applying a voltage directly to its terminals. Therefore, VCOs are widely used in many fields such as radio frequency systems and RF/microwave circuitry as well as system timing, control and reference functions. Typical applications include frequency synthesizers, mixing, VHF and UHF oscillators, carrier and subcarrier generation, FM and PM modulation, phase shift keying, clock multiplication, phase locked loops and similar areas.

The CVCO55CL-1073-1086 VCO operates between 1073-1086MHz and can be tuned with a control voltage of 0-2.2V. This VCO is suitable for frequency synthesizers, PLL clock synthesis and other digital applications.

The working principle of the CVCO55CL-1073-1086 is based on a bipolar process. The VCO is composed of an oscillator and a frequency and amplitude multiplier, both based on bipolar transistor technology. The oscillator is powered by an external DC bias voltage and a low frequency AC voltage. The combination of these two inputs will determine the oscillator\'s operating frequency. The AC voltage is adjusted using the control voltage from 0-2.2V to control the oscillator frequency. The frequency multiplier is also powered by an external DC bias voltage and the output signal from the oscillator, to generate the output signal of 1073-1086MHz.

The CVCO55CL-1073-1086 exhibits remarkable stability and frequency accuracy. It features low phase noise and low pull-in range. The oscillator requires an input voltage of 5.8-7.2V and consumes an average of only 7mA current. Moreover, it has a low EMI emission, which is favorable for digital applications. The VCO comes in a miniature and RoHS compliant 4-pin ceramic SMD package, making it convenient for handheld devices, cellphones and other digital equipment that require a narrowband VCO.

The CVCO55CL-1073-1086 is a highly reliable VCO suitable for a variety of applications where frequency synthesis, PLL clock synthesis and other digital needs are needed. It is a bipolar process based voltage controlled oscillator, making it highly stable, accurate and with very low pull-in range. It also features a low EMI emission and is available in a miniature and RoHS compliant 4-pin ceramic SMD package, making it suitable for handheld devices, cellphones and other digital equipment.
