FUNCTIONAL DESCRIPTION  
PIN DESCRIPTIONS  
The DDU12H-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 (See Table). For dash  
numbers less than 20, the total delay of the line is measured from T1 to  
T10. The nominal tap-to-tap delay increment is given by one-ninth of the  
IN  
T1-T10 Tap Outputs

Signal Input  
total delay, and the inherent delay from IN to T1 is nominally 1.5ns. For dash numbers greater than or  
equal to 20, the total delay of the line is measured from IN to T10. The nominal tap-to-tap delay increment  
is given by one-tenth of this number.
