Highly Accurate Programmable Delay Line Achieves ±3ns Integral Nonlinearity (INL)
Note to Editor:
- The DS1124 is the first serially programmable, 8-bit silicon delay line to specify delay tolerance from input to output.
- This product features an integral nonlinearity (INL)—or maximum deviation from a straight line drawn from step 0 to step 255—of ±3ns.
- The DS1124 is ideal for delaying the horizontal sync (HSYNC) pulse in large-format LCD TVs in order to achieve higher-resolution displays.

SUNNYVALE, CA—October 15, 2007—Maxim Integrated Products (Pink Sheets: MXIM) 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. This high accuracy makes the DS1124 ideal for delaying the horizontal sync pulse in large-format liquid-crystal displays (LCDs).
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 12.5MHz 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).
