FUNCTIONAL DESCRIPTION
PIN DESCRIPTIONS
The DDU4F-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). For dash
numbers less than 5025, the total delay of the line is measured from T1 to
T5. The nominal tap-to-tap delay increment is given by one-fourth of the

total delay, and the inherent delay from IN to T1 is nominally 3.5ns. For
dash numbers greater than or equal to 5025, 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 this number.
