This device offers superior timing accuracy and stability, allowing it to be deployed in such demanding applications.The device also provides outstanding jitter performance and is suitable for use in military and aerospace applications that require very precise timing and synchronization between multiple channels. It can also be used in data transmission applications, as it has a high-precision synchronization of multiple communication channel pairs.The SL38000CZC-31BH is a suitable solution for generating a precise reference clock for low-jitter clock distribution. Its design offers full flexibility of its output frequency and load driving capabilities for a wide range of applications.

Working Principle

The SL38000CZC-31BH is based on the principle of phase-locked loop (PLL) frequency synchronization. When an external reference clock is applied to the device, the internal PLL circuit compares its frequency to the applied reference clock frequency and acts accordingly to maintain synchronization.This process involves a phase comparator which compares the phase of the internal clock with the phase of the reference clock and outputs a voltage level corresponding to the difference between the two phases. The voltage output by the phase comparator is then applied to the loop filter which converts the jitter-containing phase shift into a jitter-free phase adjustment.The output of the filter is then applied to a voltage-controlled oscillator (VCO) which generates an output frequency based on the applied voltage. The output frequency of the VCO is then fed back to the phase comparator, where the process of synchronization begins again. During this process, the frequency of the output clock maintained by the device is the same as that of the reference clock.

Conclusion

The SL38000CZC-31BH is an integrated clock generator, phase-locked loop (PLL), frequency synthesizer and time/phase alignment tool that provides excellent timing accuracy and stability. Its working principle is based on the PLL frequency synchronization, and its design offers full flexibility of its output frequency and load driving capabilities for a wide range of applications.
