Improve clock duty cycle
Witryna22 maj 2016 · I want to design 30% duty cycle using VHDL. My clock frequency is 50MHz and frequency divider is 500Hz. Here I attach code for 10% duty cycle. I want change this code from 10% duty cycle to 30% duty cycle. Please someone help me. Thank you. [/10% Duty Cycle] This is for testbench: May 21, 2016 #2 KlausST Super … Witryna11 sie 2005 · Re: Improve duty cycle. Generate a short pulse (impulse) for each rising and falling edge. You have then effectively doubled the frequency. Now you can divide/2 to get your 50% duty cycle. It is easy to make an edge detector with RC and inverter gate. Then OR the pulses from 2 gates to get the X2 output for the F/F.

Witryna13 paź 2024 · A clock oscillator module requires no more than power connections with a bypass capacitor to produce a square wave output at approximately 50% duty cycle (for example, 45-55% guaranteed). You just need to pick one that is suitable for your desired frequency, supply voltage, output type and accuracy/stability. Witryna13 paź 2008 · Do these crystal oscillators 'shape up' and give a better duty cycle (not to mention clock jitter) at full operating voltage? One solution is to get a crystal oscillator at twice the desired frequency and then run it to a flip-flop, that should get you 50/50 at the desired freq.

WitrynaXOR the delayed signal with the original and that gives you a pulse on up/down ticks, AND that signal with the original and you should the up tick pulse only, aka a close to 0% duty cycle square wave. Increase the number of delays to increase the duty cycle up to 50%, invert the signal to give 50% to 100% duty cycle. WitrynaA 2Mhz clock has a 500ns period, so is high for 250ns. With a 16Mhz logic analyser you are taking samples every 62.5ns, so ideally you'd see 4 high samples, 4 low samples repeating. Now consider the effect of a minuscule 0.5% difference in frequency on the CPU oscillator, so the divider network down to the SPI bus now runs with a 251.25ns …
