DESCRIPTION
The DS1135L series is a low-power, 3V high-speed version of the popular DS1013, DS1033, and
DS1035 series.
The DS1135L series of delay lines have three independent logic buffered delays in a single package. The
device is our fastest 3-in-1 delay line. It is available in a 150-mil 8-pin SO.
The device features precise leading and trailing edge accuracy. It has the inherent reliability of an all-
silicon delay line solution.
Standard delay values are indicated in Table 1.

TEST SETUP DESCRIPTION
Figure 2 illustrates the hardware configuration used for measuring the timing parameters of the DS1135L.
The input waveform is produced by a precision pulse generator under software control. Time delays are
measured by a time interval counter (20 ps resolution) connected to the output. The DS1135L output taps
are selected and connected to the interval counter by a VHF switch control unit. All measurements are
fully automated with each instrument controlled by the computer over an IEEE 488 bus.
