Highly accurate programmable delay line

23 January 2008 Electronics Technology

The new DS1124 from Maxim is a 5,0 V, 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 0,25 ns, with a delay of 20 ns at step 0 and 83,75 ns at step 255. The DS1124 features an integral nonlinearity - in other words, the maximum deviation from a straight line drawn from the step 0 delay to the step 255 delay - of ±3 ns. This high accuracy makes it suitable for delaying the horizontal sync pulse in large-format LCDs.

The DS1124 can delay signals up to 12,5 MHz and operates from 4,75 V to 5,25 V. Packaged in a 10-pin microMAX, it is fully specified over the -40 to +85°C temperature range.
