Programmable oscillators are a type of electronic component that is capable of providing a range of signals with varying frequency, amplitude, and phase. They are used in a wide variety of applications, from measuring and controlling the timing of industrial processes to transmitting data in communication systems. The CPPT7-HZ0PT is a programmable oscillator designed for use in high-speed applications. In this article, we will discuss its application field and working principle.

Application Field

The CPPT7-HZO0PT is designed for applications that require high-speed and high-accuracy timing signals. It offers a wide range of output frequencies and phase shifts, with edges up to 1GHz and phase shift resolution up to 142.96 ps. The edge rates and phase shifts can be independently programmed in steps of 1ps, making it suitable for extremely fast data transfer applications. Additionally, the CPPT7-HZ0PT has built-in ESD protection, making it suitable for use in industrial and automotive applications.

Working Principle

The CPPT7-HZ0PT is based on a technology known as phase-locked loops (PLLs). It uses a voltage-controlled oscillator (VCO) to generate a wide range of frequencies, which are locked to a reference frequency. The PLL then allows for precise and independent control of the output frequency and phase shift of the generated signal. The device can be programmed to generate multiple different signals at different frequencies and different phase shifts, while ensuring that they are all in phase with each other.

The CPPT7-HZ0PT operates using a control voltage, which is used to program the output frequencies and phase shifts. The control voltage can be adjusted using an external signal or by programming the device through an I2C or SPI interface. Once programmed, the PLL ensures that the output frequencies remain locked to the reference frequency for the duration of the programmed period.

In addition to providing precise and independent control of output frequencies and phase shifts, the CPPT7-HZ0PT also provides jitter reduction, phase noise suppression, and power optimization features. It is capable of automatically switching between low-power mode and full-power mode, depending on the application, and can also be programmed to generate one or more phase-controlled output signals.

Conclusion

The CPPT7-HZ0PT is a programmable oscillator designed for use in high-speed applications that require precise timing signals. It operates using a phase-locked loop technology, allowing for independent control of output frequencies and phase shifts. It offers ESD protection, jitter reduction, and power optimization features, making it suitable for use in a variety of applications.
