DS1124
5.0V 8-Bit Programmable Timing Element
Ideal for Delaying the Horizontal Sync (HSYNC) Pulse in Large Format LCD TVs to Achieve Higher Resolution Displays.
|
Status
Active: In Production.
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.
