  W181-01G Application Field and Working Principle

The W181-01G clock module is designed to provide a single-frequency clock output for applications requiring a low-power, ultra-low-jitter clock source. It has a wide range of applications in clock/timing-related fields, including clock generators, phase-locked loops (PLLs), frequency synthesizers and system synchronization.

Clock Generator

The W181-01G is suited for use as a clock generator. It can produce a single frequency output with a low jitter of less than 5ps. It has a wide frequency range, from 1MHz to 200MHz. The output is also clean and well-defined, which is ideal for digital applications operating with strict clock timings.

Phase-Locked-Loops

The W181-01G is an ideal module for phase-locked-loops (PLLs). It is capable of phase-locking onto an external reference and maintaining a low-jitter output. The PLL operation can be set to free-running or locked. In free-running mode, the output frequency is determined by the internal oscillator while in locked mode, the output frequency is determined by the external reference.

Frequency Synthesizer

The W181-01G is a suitable module for use as a frequency synthesizer. It can be programmed to generate a number of discrete frequencies. The output frequencies are generated through a combination of divider and programmable oscillator blocks. This allows for a wide range of frequencies to be generated in a very small package.

System Synchronization

The W181-01G is suitable for use in applications requiring system synchronization. It can be programmed to synchronize its internal oscillator with an external clock. This allows for high accuracy synchronizing across multiple systems.

Working Principle

The W181-01G module uses a programmable oscillator to generate a single frequency clock output. The oscillator can be programmed to generate a fixed frequency, or locked to an external reference. The module is also equipped with a divider which can be used to generate lower frequency clock outputs. The output clock is passed through a low-pass filter to reduce jitter and give a clean, well-defined signal.

Conclusion

The W181-01G is a low-power, ultra-low-jitter clock module suitable for use in a variety of clock/timing-related applications, including clock generators, PLLs, frequency synthesizers, and system synchronization. The module is capable of generating up to 200MHz clock output, with low jitter and high accuracy. It is an ideal solution for applications requiring a reliable and precise clock source.
