CB3-2I-41M65714

Oscillators

The CB3-2I-41M65714 oscillator is a modern phase-locked loop (PLL) device built on bipolar silicon integrated circuit (IC) technology. The CB3-2I-41M65714 is designed to meet the frequency control requirements of portable transceiver and communications systems. It has a wide frequency range from 10 MHz to 4400 MHz and is also capable of driving high gain amplifiers up to 600 mA.

Application Field

One of the primary applications of the CB3-2I-41M65714 is as a voltage-controlled oscillator (VCO) in GPS systems. It is designed to be used in a variety of other applications including television receivers, cell phones, and pagers. It can also be used as part of the local oscillator (LO) chain in satellite uplink systems.

The CB3-2I-41M65714 is also well suited for military and space applications. It has a wide RF power output range and robust shielding to protect against electromagnetic interference (EMI). It is also resistant to single event upsets (SEU) and other radiation effects.

Working Principle

The CB3-2I-41M65714 uses a phase-locked loop (PLL) circuit to generate the desired output frequency. The PLL contains a reference oscillator, an integer- or fractional-N divider circuit, and a voltage-controlled oscillator (VCO). The reference oscillator supplies the reference frequency, which is then divided by the divider circuit output. The output of the divider is compared to the reference frequency in the phase detector, which produces an error signal that is used by the loop filter to control the voltage on the VCO. The VCO then produces the desired output frequency.

The frequency of the output signal is controlled by an external frequency control voltage. The frequency can be changed quickly and accurately to meet the requirements of the application. Additionally, the CB3-2I-41M65714 has an input for an external modulation signal which can be used to frequency modulate the output signal.
