Clock Frequency to Rise Time Calculator

This page provides information about a clock frequency to rise time calculator. It explains the formula used for clock frequency to rise time conversion and vice versa.

Clock Frequency versus Rise Time

For a re-created square wave containing only a limited number of higher harmonics, bandwidth is inversely proportional to the rise time. The illustration below depicts rise time in a square waveform with approximately a 50% duty cycle.

BW = 0.35/RT

Where:

• BW is the bandwidth of a signal in GHz
• RT is the 10 to 90% rise time in nsec

Rise Time to Clock Frequency Converter

The calculator below converts rise time to clock frequency.

EXAMPLE:

• INPUT: Rise time = 0.9 nsec
• OUTPUT: Clock Frequency = 0.11 GHz
