FUNCTIONAL DESCRIPTION

The DDU11H-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 10, 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 1.5ns. For dash numbers greater than or

equal to 10, 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.
