Understanding Clock Management DesignFollow article
Clock management for an electronic system involves understanding and optimising the design to meet all of the accuracy requirements throughout the system.
Why is Clock management needed? Clocks are used in nearly every automated system where measurement, communication and interactions are required. They have formed the starting points for travel and moved on to the heart of our modern electronic control systems. As the systems have got more complex the accuracy requirements have increased. It is now important that the timing source is very accurate and stable but also that this stability is maximised throughout the complete electronic system that this clock is used in.
A typical systems will consist of :-
Interconnection /Back plane
Additional clock distribution
A central clock generator is used this is distributed using circuits, back planes and additional distribution circuits to reach the end devices. These will typically be CPU’s, ASIC’s, FPGA’s, Memory etc.
Typical clock system
These individual elements, together with the specific issues and solutions are discussed in more detail in the attached ON Semiconductor Technical Note by Paul Hunt.
RS Components has a full range of the latest timing devices from ON Semiconductors with a focus on the PCIe bus components which provide specific solutions to ensure your designs are optimised to give the accuracy required in your applications. Areas include: Clocks including differential fan out types and data drivers. Differential switches and Low capacitance ESD protection diodes.
