FUNCTIONAL DESCRIPTION

PIN DESCRIPTIONS

The DDU66C-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 40,

VDD

+5 Volts

the total delay of the line is measured from T1 to T5, with the nominal value

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 8.0ns. For dash numbers greater than or equal to 40, 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.

APPLICATION NOTES

HIGH FREQUENCY RESPONSE

The DDU66C 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

Delay Devices if your application requires device testing at a specific input condition.

POWER SUPPLY BYPASSING

The DDU66C 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.
