Programmable Delay Line achieves ±3 ns integral nonlinearity.November 26, 2007 -
Suited for delaying horizontal sync (HSYNC) pulse in large-format LCD TVs, Model DS1124 is serially programmable, 5.0 V, 8-bit silicon delay line that can specify delay tolerance from input to output. Nominal delay per step is 0.25 ns, with delay of 20 ns at step 0 and 83.75 ns at step 255. It can delay signals up to 12.5 MHz, and operates from 4.75-5.25 V. Packaged in 10-pin MAX®, unit is fully specified over -40 to +85°C industrial temperature range.

Highly Accurate Programmable Delay Line Achieves ±3ns Integral Nonlinearity (INL)
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 MAX®, 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).
