SMD Com. SMD Mil. SMD Mil. SMD PIN DESCRIPTIONS The DDU66F-series device is a 5-tap digitally buffered delay line. The IN Signal Input signal input (IN) is reproduced at the outputs (T1-T5), shifted in time by an T1-T5 Tap Outputs amount given by the device dash number. For dash numbers less than 25, VCC +5 Volts the total delay of the line is measured from T1 to T5, with the nominal value GND Ground given by the dash number. The nominal tap-to-tap delay increment is given by 1/4 of this number. The inherent delay from IN to T1 is nominally 3.5ns. For dash numbers greater than or equal to 25, the total delay of the line is measured from IN to T5, with the nominal value given by the dash number. The nominal tap-to-tap delay increment is given by 1/5 of this number.

DATA DELAY DEVICES, INC. 3 Mt. Prospect Ave. Clifton, NJ 07013 1 DDU66F APPLICATION NOTES Delay Devices if your application requires device testing at a specific input condition. HIGH FREQUENCY RESPONSE The DDU66F tolerances are guaranteed for input pulse widths and periods greater than those specified in the test conditions. Although the device will function properly for pulse widths as small as 40% of the total delay and periods as small as 80% of the total delay (for a symmetric input), the delays may deviate from their values at low frequency. However, for a given input condition, the deviation will be repeatable from pulse to pulse. Contact technical support at Data POWER SUPPLY BYPASSING The DDU66F relies on a stable power supply to produce repeatable delays within the stated tolerances. A 0.1uf capacitor from VCC to GND, located as close as possible to the VCC pin, is recommended. A wide VCC trace and a clean ground plane should be used.
