The DS1088LU-737/T+W is a sophisticated clock generator and timing device. It combines a crystal oscillator and an on-chip phase-locked loop (PLL) to create a highly accurate and stable source of timing signals. This combination makes the DS1088LU-737/T+W an ideal solution for a wide range of timing and synchronization applications.

Application Field

The DS1088LU-737/T+W is commonly used for timing applications and clock synchronization in digital systems. It features a wide range of output frequencies, from 0.2 MHz to 120 MHz, and an on-chip PLL that can be tuned to match most system references. It also has an adjustable output skew and on-chip temperature compensation that can be used to reduce the total jitter of the generated clock signal.

The DS1088LU-737/T+W also provides a very low output noise, making it suitable for sensitive applications such as communications, data storage, and test & measurement. It also provides a wide range of phase noise injected in the output signal, which makes it suitable for jitter sensitive applications such as data transmission, high-performance computing, and broadcasting.

Working Principle

The DS1088LU-737/T+W comprises a crystal oscillator and an on-chip phase-locked loop (PLL). The crystal oscillator is used as the reference source for timing and synchronization, while the PLL is used to fine-tune the output frequency and generate the desired clock signal. The PLL includes an on-chip loop filter, which filters out high-frequency noise from the input signal and ensures low output jitter. The output clock signal is then divided by an on-chip divider to generate the desired frequency.

The DS1088LU-737/T+W also includes an on-chip temperature-compensated voltage-controlled oscillator (TCVCXO), which can be used to further reduce the output jitter. The TCVCXO is connected to the main crystal oscillator and uses its output signal as a reference. The output of the TCVCXO is then multiplied by a voltage-controlled multiplier to generate the desired frequency.

The DS1088LU-737/T+W also includes an integrated delay line and an adjustable duty-cycle output. The delay line is used to create an offset between the rising and falling edges of the output signal, while the adjustable duty-cycle output can be used to fine-tune the duty-cycle of the output signal. This combination can be used to achieve very low output jitter, reducing the output signal’s total harmonic distortion.

The DS1088LU-737/T+W also has an on-chip phase-noise receiver and error-detection circuitry. The phase-noise receiver detects and filters out high-frequency noise, while the error-detection circuitry ensures the accuracy of the clock signal. This combination helps to ensure that the output clock signal is highly accurate and stable.

Conclusion

The DS1088LU-737/T+W is a sophisticated clock generator and timing device. It combines a crystal oscillator and an on-chip PLL to create a highly accurate and stable source of timing signals. The device also includes an adjustable output skew, on-chip temperature compensation, and an integrated delay line, which can be used to further reduce output jitter. These features make the DS1088LU-737/T+W an ideal solution for a wide range of timing and synchronization applications.
