Is my design a high speed board design?
With increasing demands for higher data rates and bandwidths of the signals over wired and wireless communications, more and more digital boards are now falling in to the category of “HIGH SPEED DIGITAL BOARDS”. There are critical issues associated with high speed digital boards if those boards are not handled appropriately during design and development phases of the product development. This can lead to iterations in the product design cycle and affect the bottom lines of the product development projects. Therefore the first step in order to avoid this situation is to answer following question:?“Is my design High Speed Digital board design?”
?Here is how you can get an idea about your category of digital board design: Low speed digital board design or high speed digital board design, during your board design activity. Following three parameters of the design will define the category of digital signal speed: Propagation delay of a medium, Rise time of a signal and trace length of a signal on board.
?Let’s understand these three parameters first and then we will try to understand the correlation to find out the speed of the signal.
