FUNCTIONAL DESCRIPTION
The DDU8C-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 determined by the device dash number (See Table). 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 the total delay.
