Frequently Asked Question

On the AD9510, how can I make sure that the duty cycle of output clocks stays within 40% to 60% duty cycle window?

A divide-by-3 will produce a duty cycle of 33.3%-66.6%. A divide-by-5 produces exactly 40%-60%. Higher odd divide ratios (7, 9, 11...) produce duty cycles within the 40%-60% window.
