... 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. LCD Televisions ...

... CLK clocks the data, D, into the register one bit at a time starting with the most significant bit. After all 8 bits OUT are shifted into the DS1124, E must be pulled low to end the data transfer and activate the new value. A settling time (t EDV signal delay will meet its specified accuracy ...

... Use high-quality, ceramic, surface mount capacitors, and mount the capacitors as close as possi- ble to the V and GND pins of the DS1124 to minimize CC lead inductance. The DS1124 may not perform as speci- fied if good decoupling practices are not followed. Timing Element t EH NEW BIT 0 ...
