The ON Semiconductor NB7V585MMNR4G is a high-performance, low skew 2:1 differential-to-LVPECL/ECL Clock Multiplexer which is designed to meet the needs of high-speed data communication systems. This clock buffer is part of ON Semiconductor's extensive range of clock generation and distribution products, known for their reliability and precision.

Operating within a voltage range of 2.375V to 3.465V, the NB7V585MMNR4G is suitable for a variety of applications, including networking, telecommunications, and high-speed computing. It is capable of handling clock frequencies up to 3GHz with minimal skew, which ensures that the timing of signals across the system remains synchronized and stable.

This device features two selectable differential clock inputs which can be controlled via the input select pin. The selected clock input is distributed to two differential outputs, which can be used to provide a consistent clock signal to multiple parts of a system. The device also offers a fail-safe function, which ensures that the outputs maintain a high impedance state when the inputs are left open.

The NB7V585MMNR4G comes in a compact 16-pin QFN package, making it ideal for space-constrained applications. Its small footprint does not compromise on performance, with specifications that include a typical additive phase jitter of 0.2 ps (rms), and a propagation delay of 200 ps (max). This makes it a suitable choice for high-performance systems where timing accuracy is critical.

Furthermore, the device incorporates power-saving features. It has a standby current of 1 µA (typical) which helps reduce overall power consumption when the device is not in active use. This makes the NB7V585MMNR4G an energy-efficient solution for modern electronic systems.

Overall, the ON Semiconductor NB7V585MMNR4G Clock Buffer is a highly reliable and precise solution for clock distribution in high-speed data systems. Its combination of performance, efficiency, and small package size makes it an excellent choice for designers looking to optimize their system's clock architecture.
