The original is not, there is a close variant still in production: https://www.maximintegrated.com/en/products/analog/clock-generation-distribution/DS1124.html "The DS1124 is an 8-bit programmable timing element similar in function to the DS1021-25. The 256-delay intervals are programmed by using a 3-wire serial interface. With a 0.25ns step size, the DS1124 can provide a delay time from 20ns up to 84ns with an integral nonlinearity of ±3ns. " Small package, would be a little difficult to prototype by hand, but not impossible. -- Chris Caudle _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
