FUNCTIONAL DESCRIPTION
PIN DESCRIPTIONS
The DDU8C3-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 5020 and above, the total delay of the line is measured from IN to
T5, and the nominal tap-to-tap delay increment is given by one-fifth of the

total delay. For dash numbers below 5020, the total delay is measured from T1 to T5, and the delay
increment is given by one-fourth of the total delay.
