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. 1 of 6 19-6412 Rev 8/12 DS1135L LOGIC DIAGRAM Figure 1 IN OUT TIME DELAY ONE OF THREE PART NUMBER DELAY TABLE (t , t ) Table 1 PLH PHL TOLERANCE OVER DELAY PER INITIAL TEMP AND VOLTAGE PART NUMBER OUTPUT TOLERANCE (Note 2) (ns) (Note 1) 0C to +70C -40C to +85C 10/10/10 DS1135LZ-10+ 1.0ns 2.0ns 3.0ns DS1135LZ-12+ 12/12/12 1.0ns 2.0ns 3.0ns DS1135LZ-15+ 15/15/15 1.0ns 2.5ns 4.0ns DS1135LZ-20+ 20/20/20 1.0ns 2.5ns 4.0ns 25/25/25 DS1135LZ-25+ 1.5ns 3.0ns 5.0ns 30/30/30 DS1135LZ-30+ 1.5ns 3.0ns 5.0ns +Denotes a lead(Pb)-free/RoHS-compliant package. NOTES: 1. Nominal conditions are +25C and V = +3.3V. CC 2. Voltage range of 2.7V to 3.6V. 3. Delay accuracies are for both leading and trailing edges. 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. 2 of 7
