FUNCTIONAL DESCRIPTION

The DDU18-series device is a 8-tap digitally buffered delay line. The signal input (IN) is reproduced at the outputs (T1-T8), shifted in time by an amount determined by the device dash number (See Table). For dash numbers less than 16, the total delay of the line is measured from T1 to T8. The nominal tap-to-tap delay increment is given by one-seventh of the total delay, and the inherent delay from IN to T1 is nominally 2.0ns. For dash numbers greater than or equal to 16, the total delay of the line is measured from IN to T8. The nominal tap-to-tap delay increment is given by one-eighth of this number.
