DESCRIPTION
The DS1135L series is a low-power, 3V high-speed version of the popular DS1013, DS1033, DS1035
series.
The DS1135L series of delay lines have three independent logic buffered delays in a single package. The
device is Dallas Semiconductor’s fastest 3-in-1 delay line. It is available in a standard 8-pin 118mil
µSOP and 150mil 8-pin Mini-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. Customers may contact Dallas Semiconductor at (972)
371-4348 for further information on custom delay values.

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.

TERMINOLOGY
Period: The time elapsed between the leading edge of the first pulse and the leading edge of the
following pulse.
tWI (Pulse Width): The elapsed time on the pulse between the 1.5V point on the leading edge and the
1.5V point on the trailing edge or the 1.5V point on the trailing edge and the 1.5V point on the leading
edge.
tRISE (Input Rise Time): The elapsed time between the 20% and the 80% point on the leading edge of the
input pulse.
tFALL (Input Fall Time): The elapsed time between the 80% and the 20% point on the trailing edge on the
input pulse.
tPLH (Time Delay, Rising): The elapsed time between the 1.5V point on the leading edge of the input
pulse and the 1.5V point on the leading edge of the output pulse.
tPHL (Time Delay, Falling): The elapsed time between the 1.5V point on the falling edge of the input
pulse and the 1.5V point on the falling edge of the output pulse.
