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 allsilicon 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.
