Programmable Delay Line

Maxim Integrated Products introduces the DS1124 5.0V, 8-bit programmable delay line that features a 3-wire serial interface to allow cascading of several devices for multiple programmable delays. The nominal delay per step is 0.25ns, with a delay of 20ns at step 0 and 83.75ns at step 255. The DS1124 features an integral nonlinearity (INL)—or maximum deviation from a straight line drawn from the step 0 delay to the step 255 delay—of ±3ns over the industrial temperature range.

 The DS1124 can delay signals up to 12.5MHz and operates from 4.75V to 5.25V. Packaged in a 10-pin µMAX, the DS1124 is fully specified over the -40°C to +85°C industrial temperature range. Prices start at $1.70 (10,000-up, FOB USA).
