The NB7LQ572MNG is one such device that is widely used in those industries. The application field and working principle of the NB7LQ572MNG are outlined below in this article.

Application Field

The NB7LQ572MNG is a low-power Clock/Timing - Clock Buffer and Driver, which can switch between one clock reference and another. It is primarily used in applications such as PCS, communications and consumer electronics products. It can also be used in portable audio and video products, multimedia, monitors, televisions and printers. The device operates from a single-ended or differential clock source, with a single differential output, and is able to switch between up to two clock sources. The NB7LQ572MNG offers excellent jitter performance, low power consumption and a wide range of frequencies from 25-188MHz.

Working Principle

The NB7LQ572MNG provides excellent jitter performance and low power consumption for various applications. It provides an adjustable propagation delay, allowing predictable timing behavior in multiple clock domains. The device has a variable voltage range, allowing it to operate over a wide range of supply voltages while maintaining a low stand-by current. It also has an adjustable output edge rate, which can be set independently for rise and fall times, allowing for flexible output waveform shaping.

The device includes internal power-on reset (POR) circuitry with an adjustable reset window, which ensures reliable system startup and prevents random output glitches. The NB7LQ572MNG can switch between up to two clock sources with a single differential output. The switching process is controlled by an external control input and the device can switch from one reference clock to another within 800ns.

The device also features a selectable slew rate, which allows for slower edge rates for improved jitter performance. The NB7LQ572MNG supports differential, pseudo-differential and single ended clocks, and can be used as a clock generator for many applications. It also offers a wide frequency range from 25-188MHz, allowing for a wide range of clock sources.

Conclusion

The NB7LQ572MNG is a low-power Clock/Timing - Clock buffer and driver, which offers excellent jitter performance and low power consumption for a wide range of applications. It provides adjustable propagation delay, internal power-on reset circuitry, adjustable output edge rate and adjustable reset window. The device can switch between up to two clock references, with a wide frequency range from 25-188MHz. Overall, the NB7LQ572MNG is an excellent choice for a wide range of clock/timing applications, and offers excellent jitter performance, low power consumption and a wide range of frequencies.
