Maxim Integrated Products has unveiled the DS1124, a 5V, 8bit 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 device features an integral nonlinearity—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. This high accuracy makes the DS1124 suited for delaying the horizontal sync pulse in large-format LCDs.

In addition, DS1124 is the touted to be the first programmable delay line to specify delay tolerance from input to output, rather than to a reference output signal. It can delay signals up to 12.5MHz and operates from 4.75- 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 Rs.68.76 ($1.70) (10,000-up, FOB USA).
