Useful design equations for the PT2399

Posted by & filed under Stompbox stuff.

The PT2399 datasheet gives some data showing the relationship between the resistor on pin 6, the clock frequency, and the delay time. Unfortunately, it doesn’t offer any design equations relating these three variables. So, can we derive some? Yes, we can! They’re all included here. First, a quick summary of what I’ve learned, if you want to cut to the chase: Delay msecs = (11.46 * Resistance KΩ) + 29.70 Delay msecs = (683.21 / Clock Freq MHz) + 0.08… Read more »
