DS1124

www.DataSheet4U.com Rev 0; 7/07 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 interface. With a 0.25ns step size, the DS1124 can provide a delay time from 20ns up to 84ns with an integral nonlinearity of ±3ns. ♦ 0.25ns Step Size ♦ Leading- and Trailing-Edge Accuracy ♦ CMOS/TTL Compatible ♦ Can Delay Signals by a Full Period or More ♦ 3-Wire Serial Programming Interface ♦ Single 5.0V Power Supply ♦ 10-pin µSOP Package Features DS1124 Applications LCD Televisions Telecommunications Digital Test Equipment Digital Video Projection Signal Generators and Analyzers Pin Configuration TOP VIEW + IN 1 E Q GND GND 2 3 4 5 10 VCC 9 VCC D CLK OUT Ordering Information PART DS1124U-25+ TEMP RANGE -40°C to +85°C PIN-PACKAGE 10 μSOP 10 μSOP (Tape-and-Reel) DS1124U-25+T -40°C to +85°C +Denotes a lead-free package.
