It is able to provide an output frequency range from 250kHz up to 649MHz with an accuracy of +/-10 ppm (parts per million). This level of accuracy is necessary for many critical timing applications, such as real-time embedded computing and military-grade precision circuit design.

Features & Benefits

The PT7V40283-A1-5GWF features several features and benefits that make it ideal for use in a variety of applications. It is powered by an internal low-power 32-bit RISC processor and includes an embedded frequency synthesizer, temperature sensor, and flexible register programming to enable dynamic pro gramming of output frequencies and phase-locked loops (PLLs). Additionally, the timer and oscillator is programmable over a wide range of voltages, temperatures, and f requencies. This allows it to easily adapt to a variety of environments and ensure that the output frequency remains consistent and accurate. The timer also includes integrated loop filters, which provide a high level of noise reduction and ensure stable and long-term frequency output. Furthermore, the PT7V40283-A1-5GWF features wide operating temperature range (from -40°C to +125°C (-40°F to +257°F)), small size, low power consumption and integrated IP protection for increased data security.

Working Principle

The PT7V40283-A1-5GWF is based on a frequency-synthesis architecture (FS-MUX Architecture) which provides a high degree of accuracy and stability. The working principle employs a programmable voltage-controlled oscillator (VCO) to generate a base signal, which is then divided down to the required output frequency.The programmability is achieved by the use of an internal lookup table and calibration routine to provide a programmed voltage for a given input frequency. This ensures that the output frequency is as accurate as possible. In order to ensure that the output signal remains accurate and stable, the oscillator uses a phase-locked loop (PLL) to regulate the frequency of the output signal. A digital signal processor (DSP) is used to control the PLL and minimize the signal jitter. This ensures that the output signal remains stable and accurate over long periods of time.

Conclusion

The PT7V40283-A1-5GWF is a highly accurate programmable timer and oscillator designed for a wide range of applications. Its application field includes a variety of fields, such as frequency synthesis, synchronization and timing accuracy, feedback control systems, automotive and avionics applications, digital signal processing, and communications systems, among others. The working principle of the oscillator employs a frequency synthesis architecture, which ensures a high degree of accuracy and stability. The oscillator also features a wide operating temperature range, small size, low power consumption, integrated IP protection for increased data security, and integrated loop filters for reduced noise. These features make the timer and oscillator ideal for a variety of applications that require highly accurate and reliable frequency output.
