The NBSG111BAHTBG integrated circuit is used in the Clock/Timing category of electronics for a variety of applications. It is an advanced clock buffer that is designed to provide reliability, accuracy and optimal power consumption in critical time-sensitive environments. It allows for multiple distributed clock signals by buffering the reference clock input and sending out adjusted clock signals. It is a multifunctional device that can provide multiple kinds of outputs such as sine wave outputs and enable/disable signals at different rates, making it suitable for a variety of applications. This device is always used for the purpose of efficiently distributing a single clock among several slaves.The clock buffer is built on the same technology used in other Integrated Circuits and draws on both digital and analog design concepts. The circuit is designed to accurately amplify a reference clock input and provide buffer copies based on the clock’s frequency. The circuits also feature low-skew outputs, jitter tolerant inputs, and both differential and single-ended outputs. The buffers also provide adjustable output levels, backed by a high power supply rejection ratio. The buffer chip also contains a Start-Up bypass feature, making it suitable for use in power-sensitive systems.

In the NBSG111BAHTBG Integrated Circuit, a Multiple Clock Tree (MCT) based architecture is used for the clock distribution design. The architecture is comprised of trees of clock buffers, each of which receive a single-ended clock input and provide multiple copies at different clocking rates. This allows the system to take advantage of low-skew outputs, enabling timing-critical systems to achieve more accurate results.

Working Principle

The working principle of the NBSG111BAHTBG is based on the concept of a cascaded-tree network of clock buffers. A single clock signal is routed to the root of the clock tree, and the processed signals are then routed to multiple branches, each corresponding to a slave in the system. The buffer copies are adjusted so that each slave receives an input with an accurate timing, as well as low-skew outputs. This allows the system to adjust the clocking rate of each slave and quickly switch between different signals.

The clock tree is designed to be tolerant to any variation in the reference clock input, such as frequency changes, jitter and temperature drifts. This ensures that any change in the reference clock input is handled appropriately and none of the buffer outputs is affected by the variation. The buffers also have a high power-supply rejection ratio, ensuring that the output signals remain valid and accurate even during changes in the power supply voltage.

The NBSG111BAHTBG is an ideal product for applications that require accurate timing signals, such as processors, bus interfaces, and other components in computer systems and communication networks. As the clock speed increases, the number of buffer copies increases accordingly, ensuring that all the components in the system receive valid and accurate data.

In addition, the clock buffer chip provides a Start-Up bypass feature, which allows the device to quickly and accurately power up, eliminating delay and clock disconnects during start-up. This feature also reduces power consumption while the system is idle, making it suitable for use in power-sensitive systems.
