Rev 1; 4/09
5.0V 8-Bit Programmable
Timing Element
General Description
The DS1124 is an 8-bit programmable timing element
similar in function to the DS1021-25. The 256-delay
intervals are programmed by using a 3-wire serial inter-
face. With a 0.25ns step size, the DS1124 can provide
a delay time from 20ns up to 84ns with an integral non-
linearity of ±3ns.
