Oscillators

An oscillator is a device, circuit, or system that generates a recurring waveform, usually a sine wave or a square wave. Oscillators are widely used in many electronic and mechanical systems for generating sound, measuring frequencies, generating signals, powering transmitters, and providing time reference signals. Oscillators are also used in modern applications such as for generating clock signals, handling encoding and decoding data, producing precision measurements, and powering computers.

Working Principle of BB75070001

The working principle of BB75070001 is based on its PLL (phase-locked loop) architecture. It consists of two parts: the voltage-controlled oscillator and the divider. The VCO generates an instantaneous frequency whose output is proportional to the input voltage. The divider is used to divide down the frequency of the VCO to match the actual frequency of the signal that the system is generating. The frequency is monitored by the loop filter, which adjusts the VCO output frequency to match the signal’s frequency by controlling the output voltage.

The loop filter is used to control the output voltage of the VCO. It consists of low-pass filters or active filters that measure the difference between the input and output frequency of the VCO. The filter is used to convert from a voltage controlled frequency to a voltage controlled phase by rectifying the signal. The feedback from the divider is used to adjust the output voltage of the VCO to match the input frequency.

BB75070001 can generate a frequency range of 6.4MHz to 3000MHz with a resolution of 500kHz. It has a fast locking time of up to 25ns and can maintain its frequency accuracy of up to 0.1%. Additionally, it is resistant to jitter and offers great stability and reliable performance.
