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 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 microMAX(R), the DS1124 is fully specified over the -40 degrees Celsius to +85 degrees Celsius industrial temperature range. Prices start at $1.70 (10,000-up, FOB USA).

Features

• 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.
