The DS1050Z-005+ (hereafter referred to as the DS1050) is one of the most popular programmable timers and oscillators available in the market today. It is primarily used for timing, frequency and power supply applications. In this article, we will take a closer look at the application fields and working principles of the DS1050.

Application Fields

The DS1050 is a popular choice for timing and frequency applications. It is a high-precision, programmable timer/oscillator with a wide frequency range and high resolution. The DS1050 can be used for applications such as power supply design, clock synchronization, communications and signal conversion. In addition to these, the DS1050 can be used in applications such as frequency measurement, frequency stability testing, data recovery, motion control and precision timekeeping.

Working Principles

The DS1050 consists of two main parts: a programmable oscillator and a phase-locked loop (PLL). The oscillator is responsible for producing a stable, noise-free reference frequency that is used by the PLL to generate the desired output frequency. The PLL allows the user to control the reference frequency, thus allowing for precise tuning of the output frequency. The DS1050 also has a number of programmable features such as clock output, prescaler, power supply sequencing and power-fail detection.

The DS1050 operates in two modes: single-ended mode and differential mode. In single-ended mode, the output frequency is determined by the input frequency, while in differential mode, the output frequency is determined by the difference in the input frequencies. The input frequency can be set using the programmable on-chip clock frequency register (CFR). The CFR allows for accurate fine-tuning of the input frequency and the output frequency.

The DS1050 also has a number of features to ensure the stability and accuracy of the output frequency. These include an on-chip temperature-compensated crystal oscillator (TCXO) and an on-chip analog-to-digital converter (ADC). The TCXO can be used to reduce the power consumption of the oscillator and increase its accuracy. The ADC allows the user to fine-tune the output frequency over different environmental conditions.

Finally, the DS1050 also features a low-jitter clock output, which can be used for clock synchronization applications. The low-jitter output provides a stable, low-noise signal for controlled-slope, asynchronous reclocking operations.

Conclusion

The DS1050 is a highly versatile programmable timer/oscillator with a wide range of applications. It is used for timing and frequency applications, as well as for power supply design, clock synchronization and signal conversion. The DS1050 also features a TCXO, ADC and a low-jitter clock output, which make it well-suited for precision timekeeping and frequency stability testing.
