Programmable Oscillators

Programmable oscillators offer low power, high stability frequencies over a wide range of temperatures and frequencies. CPPLT7-HZ76P is an example of such oscillator. It is an analog-based programmable oscillator with high accuracy performance and a long life design.

Application Field

CPPLT7-HZ76P is widely used in level control, industrial automation and robotics control, pressure and flow control, and motor control applications. Oscillators of this type are also used in the entertainment industry, such as broadcasting and recording audio and video signals. Other applications include medical instrumentation, automotive, measuring, and telecommunications.

Working Principle

CPPLT7-HZ76P programmable oscillators are built using the principles of PLL (Phase Locked Loop), a technique that uses an input frequency and generates a stable output frequency within a specific range. A key feature of PLL-based oscillators is the feedback circuit, which compares the generated frequency to the reference frequency and corrects any difference between them. This allows the oscillator to maintain a high level of accuracy over a wide operating temperature range.

The oscillator consists of a voltage-controlled oscillator (VCO) that generates a signal waveform, which is shaped and divided by frequency dividers to provide the required frequency modulation and waveform stability. The waveform is then used as an input to the phase-locked loop circuit which stabilizes the waveform and provides accurate frequency modulation.

CPPLT7-HZ76P oscillators are designed to operate in temperatures from -40°C up to +85°C (15°C to +71°C for 4 pF). With an operating range of 0.25MHZ to 13MHz these oscillators are ideal for use in a wide variety of applications.

Conclusion

CPPLT7-HZ76P is a programmable oscillator used in a variety of applications. They are designed to offer high accuracy performance and long life design, over a wide operating temperature range. With a wide range of frequencies, CPPLT7-HZ76P oscillators are ideal for motor control, level control, pressure and flow control, industrial automation and robotics control, and other applications.
