FUNCTIONAL DESCRIPTION  
PIN DESCRIPTIONS  
The DDU222F-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 given by the device dash number. For dash numbers less than  
25, the total delay of the line is measured from T1 to T5, with the nominal  
value 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 3.5ns. For dash numbers  
greater than or equal to 25, 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.
