DDU4C-xxMC2 Military FUNCTIONAL DESCRIPTION The DDU4C-series device is a 5-tap digitally buffered delay line. The signal input (IN) is reproduced at the outputs (T1-T5), shifted in time by an amount determined by the device dash number (See Table). The total delay of the line is measured from IN to T5. The nominal tap-to-tap delay increment is given by one-fifth of the total delay.

Prospect Ave. Clifton, NJ 07013 1 DDU4C APPLICATION NOTES HIGH FREQUENCY RESPONSE The DDU4C 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 DDU4C relies on a stable power supply to produce repeatable delays within the stated tolerances. A 0.1uf capacitor from VDD to GND, located as close as possible to the VDD pin, is recommended. A wide VDD trace and a clean ground plane should be used.
