FUNCTIONAL DESCRIPTION

PIN DESCRIPTIONS

The DDU66F-series device is a 5-tap digitally buffered delay line. The

Signal Input

signal input (IN) is reproduced at the outputs (T1-T5), shifted in time by an

T1-T5 Tap Outputs

amount given by the device dash number. For dash numbers less than 25,

VCC

+5 Volts

the total delay of the line is measured from T1 to T5, with the nominal value

GND Ground

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.
