... U falling output edges, and the propagation delays of any two receivers within a package are very tightly matched. The precision timing features of the LTC1520 reduce overall system timing constraints by providing a narrow 6ns window during which valid data appears at the re- ceiver output. This output timing window applies to all ...

... In such applications, standard high speed CMOS logic may be used as a driver for the LTC1520. The receiver trip points may be easily adjusted to accommodate different driver output swings by changing the resistor divider at the fixed input ...

... LTC1520 used as a tapped delay line with 18ns 3ns steps. Several LTC1520s may be connected in series to form longer delay lines. Each tap in the delay line is accurate to within 17% over temperature. As shown in Figure 10, the LTC1520 can be used to create a temperature stable ring oscillator with period increments 0ns DELAY INPUT 5V 3 ...
