CDCUA877ZQLT

The CDCUA877ZQLT is a clock/timing application specific device that can be used to determine the accuracy of delay intervals across multiple devices. It utilizes a unique 8-bit delta-sigma counter to accurately measure both time-based and frequency-based intervals using a signal source and reference signal. The device provides a highly accurate and repeatable signal delay measurement result, making it ideal for a variety of clock/timing-based applications such as synchronization, timekeeping, and timing measurement.

Application Fields

The CDCUA877ZQLT was designed specifically to improve timing accuracy and precision across multiple devices. It can be used in a variety of clock/timing-based applications, including synchronization, timekeeping, and timing measurement applications. In particular, the device can be used in applications that require a precise measurement of signal delay intervals, such as synchronizing multiple clocks and devices in a network, monitoring and measuring the timing of industrial processes and systems, timing digital signal processing tasks, or analyzing the accuracy of synchronous logic designs.

The CDCUA877ZQLT can also be used in embedded systems, where devices must send and receive frequently updated data from multiple sources and destinations. By accurately measuring signal delays, the device can be used to ensure data is accurately delivered across multiple channels and devices.

Working Principle

The CDCUA877ZQLT is a delta-sigma counter, which means that it measures a signal\'s delta (difference in time or frequency of two signals) to create a very high resolution result. The device utilizes a clocking generator and low-noise delta-sigma counter to measure the time-based or frequency-based delays between two signal sources and a reference signal. The device then generates a digital result that reflects the measured delay.

The CDCUA877ZQLT can be used to measure a wide range of signal delay values, spanning from 2600 ns to 6400 ms. Its high-resolution results can provide up to 16-bit accuracy and resolution, making it ideal for applications that require precise timing, such as industrial automation and digital signal processing tasks.

The CDCUA877ZQLT also utilizes a unique calibration feature that allows the device to automatically adjust to compensate for time-varying noise and temperature-related effects on the reference signal, giving it superior long-term accuracy. This makes the device ideally suited for long-term applications, such as timekeeping, synchronization, and monitoring of industrial processes and systems.

Conclusion

The CDCUA877ZQLT is a highly accurate and repeatable clock/timing application specific device that can be used to measure time and frequency delays between two signal sources and a reference signal. It utilizes a unique 8-bit delta-sigma counter to measure these delays, providing highly accurate results of up to 16-bit resolution. The device also features an automatic calibration feature that allows it to maintain its accuracy over long periods of time, making it well-suited for a variety of clock/timing-based applications, such as synchronization, timekeeping, and timing measurements.
