The IN Signal Input signal input (IN) is reproduced at the outputs (T1-T10), shifted in time by an T1-T10Tap Outputs amount determined by the device dash number. The nominal taptotap VCG +5 Volts delay increment is given by 1/10 of the dash number. For dash numbers GND Ground less than 50, the total delay of the line is measured from T1 to 110, with the nominal value given by 9 times the increment. The inherent delay from IN to T1 is nominally 3.5ns. For dash numbers greater than or equal to 50, the total delay of the line is measured from IN to T10, with the nominal value given by the dash number.

Prospect Ave. Clifton, NJ 07013 DDU7F APPLICATION NOTES HIGH FREQUENCY RESPONSE The DDU7F 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 20% of the total delay and periods as small as 40% 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 Delay Devices if your application requires device testing at a specific input condition. POWER SUPPLY BYPASSING The DDU7F 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.
