CDCLVC1112PWR Application Field and Working Principle

The CDCLVC1112PWR is a low-voltage and low-current level-translator clock buffer from Texas Instruments. It is designed for applications that require high-precision timing at low supply voltages, such as USB-C. The device provides low-skew, low-jitter buffering and drive for reference clocks, and supports low-voltage input clocks up to 3.3V. In addition to its low power requirements, the CDCLVC1112PWR offers other helpful features, including an adjustable output slew rate, a lock detect pin, and programmable glitches for retaining debug information at power down.

Application Field

The CDCLVC1112PWR is a highly-integrated clock buffer specifically designed to support low-voltage, low-power applications. It boasts a superior noise rejection ratio and high switching frequency, making it ideal for applications such as USB-C and Type-C connectors. It is also well-suited to support data processing and communications systems, as well as industrial needs, such as medical equipment and embedded controls.

Features

The CDCLVC1112PWR offers a variety of optional features that support a range of applications. Its low-voltage input clock support enables stable operation at low supply voltages up to 3.3V. Its low-skew, low-jitter buffering and drive support reference clocks at fast speeds, and it can adjust the output slew rate to prevent data corruption due to overshoot or undershoot. It also offers a lock detect pin to inform the user when the clock is not running. Finally, it features programmable glitches to retain debug information during power-down operations.

Working Principle

The CDCLVC1112PWR is a low-power driver for reference clocks. Its integrated circuitry supports a peak operating current of only 6mA, enabling this device to operate from a wide range of power sources, including USB-C, Type-C, and other industry-standard connectors. The CDCLVC1112PWR supports low-frequency input clocks up to 3.3V. The translator converts these low-voltage clocks to the output logic level of the host system, enabling a robust and efficient connection between the system and the clock source.

The CDCLVC1112PWR uses its low-skew and low-jitter buffering technology to accurately drive the reference clock with minimal distortion. This technology provides precise and stable timing outputs that support fast data rates, while also helping to reduce system power consumption. The device also features an adjustable output slew rate, which prevents potential data corruption due to signal overshoot or undershoot during high switching frequencies.

The CDCLVC1112PWR also features a lock detect pin to signal the user when the clock is not running. Finally, the device offers programmable glitches, which can be enabled or disabled to retain debug information at power-down operations. These features make the CDCLVC1112PWR an ideal choice for high-precision applications where lesser data corruption is a requirement.

Conclusion

The CDCLVC1112PWR is a highly-integrated clock buffer from Texas Instruments. It is optimized for low-voltage and low-power applications, and provides low-skew and low-jitter buffering and drive for reference clocks at up to 3.3V. The device also offers several optional features, including an adjustable output slew rate, a lock detect pin, and programmable glitches to retain debug information at power down.
