Highly Accurate Programmable Delay Line Achieves ±3ns Integral Nonlinearity (INL)

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 is the first serially programmable, 8-bit silicon delay line to specify delay tolerance from input to output.

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. This high accuracy makes the DS1124 ideal for delaying the horizontal sync pulse in large-format liquid-crystal displays (LCDs).
