DESCRIPTION
The DS1033 series is a low-power +3.3 Volt version of the DS1035. It is characterized for operationover the range of 2.7V to 3.6V.
The DS1033 series of delay lines have three independent logic buffered delays in a single package. It isavailable in a standard 8-pin DIP, 150-mil 8-pin mini-SOIC.
The device features precise leading and trailing edge accuracies. It has the inherent reliability of an all-silicon delay line solution. The DS1033’s nominal tolerance is ±1.5 ns and an additional tolerance overtemperature and voltage of ±1.0 ns for the faster delays. Detailed specifications are shown in Table 1.Standard delay values are indicated in Table 1. Customers may contact Dallas Semiconductor at (972)371-4348 for further information.

TEST SETUP DESCRIPTION
Figure 2 illustrates the hardware configuration used for measuring the timing parameters of the DS1033.The input waveform is produced by a precision pulse generator under software control. Time delays aremeasured by a time interval counter (20 ps resolution ) connected to the output. The DS1033 output tapsare selected and connected to the interval counter by a VHF switch control unit. All measurements arefully automated with each instrument controlled by the computer over an IEEE 488 bus.
