FUNCTIONAL DESCRIPTION  
PIN DESCRIPTIONS  
The DDU7C-series device is a 10-tap digitally buffered delay line. The  
signal input (IN) is reproduced at the outputs (T1-T10), shifted in time by an  
amount determined by the device dash number. The nominal tap-to-tap  
delay increment is given by 1/10 of the dash number. For dash numbers  
less than 50, the total delay of the line is measured from T1 to T10, with the  
IN

T1-T10 Tap Outputs

nominal value given by 9 times the increment. The inherent delay from IN to T1 is nominally 8.0ns. 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.

APPLICATION NOTES  
Delay Devices if your application requires device  
testing at a specific input condition.  
HIGH FREQUENCY RESPONSE  
The DDU7C 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  
POWER SUPPLY BYPASSING  
The DDU7C 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.
