FUNCTIONAL DESCRIPTION
The DDU4C-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.
