FUNCTIONAL DESCRIPTION
PIN DESCRIPTIONS
The DDU66F-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 given by the device dash number. For dash numbers less than 25,
the total delay of the line is measured from T1 to T5, with the nominal value
given by the dash number. The nominal tap-to-tap delay increment is

given by 1/4 of this number. The inherent delay from IN to T1 is nominally 3.5ns. For dash numbers
greater than or equal to 25, the total delay of the line is measured from IN to T5, with the nominal value
given by the dash number. The nominal tap-to-tap delay increment is given by 1/5 of this number.
