Oscillators

Oscillators are devices that produce periodically repetitive electrical signals of a configured frequency. They are generally used to generate a reference signal for the purpose of frequency control, synchronization or communication applications. Oscillators, in general, are categorized according to the type of waveform they produce, among which sinusoidal oscillators, square wave oscillators, sawtooth oscillators, and triangle wave oscillators are the most common.

CPPLC7LZ-A7BR-27.0TS is an example of a sinusoidal oscillator. It is a stable, high-precision oscillator that can produce signals of a given frequency with low to moderate harmonic distortions. The CPPLC7LZ-A7BR-27.0TS oscillator consists of a capacitive load oscillator circuit integrated with a temperature-compensated reference and an operational amplifier. The circuit is powered by 3.3-24V DC supply voltage and its output frequency is tuned by the variable resistor. The oscillator features a wide temperature range of -40 to 85°C and a high storage temperature up to 125°C.

The CPPLC7LZ-A7BR-27.0TS oscillator is mainly used in radio-frequency (RF) applications such as Wi-Fi, Bluetooth, and GPS. It can also be used for clock generation circuits that provide timing signals used in communication systems, portable devices, mobile phones, digital video recorders, and other consumer electrical products. In addition, it is commonly used in frequency control applications such as motor controls and servo systems.

Working Principle: The CPPLC7LZ-A7BR-27.0TS oscillator is a reaction type oscillator that works on the principle of negative feedback. The circuit consists of an operational amplifier with its inverting terminal connected to a variable resistor. This resistor constitutes the frequency tuning control of the oscillator. The output of the amplifier is feed back to the inverting terminal through a network consisting of capacitors, resistors, and inductors. The frequency of oscillation of the oscillator is determined by the capacitance value of the network.

The oscillator is designed to operate under a stable condition of synchronization with low phase noise. It runs on a power supply of 3.3-24V DC and works optimally at supply voltages ranging from 7 to 16V DC. It also has an excellent temperature compensation feature, which ensures low harmonic distortion even at wide temperature ranges, i.e. -40 to 85°C. The CPPLC7LZ-A7BR-27.0TS oscillator is an epitome of improved performance, stability, and reliability for oscillators.
