FUNCTIONAL DESCRIPTION

PIN DESCRIPTIONS

The DDU11H-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 determined by the device dash number (See Table). For dash

-5 Volts

numbers less than 10, the total delay of the line is measured from T1 to

GND

Ground

T5. The nominal tap-to-tap delay increment is given by one-fourth of the

 

 

total delay, and the inherent delay from IN to T1 is nominally 1.5ns. For dash numbers greater than or equal to 10, 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 this number.

APPLICATION NOTES

HIGH FREQUENCY RESPONSE

The DDU11H 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 DDU11H relies on a stable power supply to produce repeatable delays within the stated tolerances. A 0.1uf capacitor from VEE to GND, located as close as possible to the VEE pin, is recommended. A wide VEE trace and a clean ground plane should be used.
