Doc #97034 DATA DELAY DEVICES, INC. 12/10/97 3 Mt. Prospect Ave. Clifton, NJ 07013 5-TAP, HCMOS-INTERFACED FIXED DELAY LINE (SERIES DDU4C)

FEATURES

Five equally spaced outputs Fits standard 8-pin DIP socket Low profile Auto-insertable Input & outputs fully CMOS interfaced & buffered

10 T2L fan-out capability

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.

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.
