8-bit programmable delay line boasts high accuracy

Sunnyvale, Calif. — Maxim Integrated Products has introduced the DS1124, a 5.0-V, 8-bit programmable delay line that features a 3-wire serial interface that allows 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 (INL)-or maximum deviation from a straight line drawn from the step 0 delay to the step 255 delay of ±3 ns over the industrial temperature range. This high accuracy makes the DS1124 suitable for delaying the horizontal sync pulse in large-format liquid-crystal displays (LCDs).

Maxim said the DS1124 is 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 12.5 MHz and operates from 4.75 V to 5.25 V. Packaged in a 10-pin microMAX, the DS1124 is fully specified over the -40°C to +85°C industrial temperature range.

Pricing: Starts at $1.70 (10,000-up, FOB USA).
Datasheet: DS1124
