FUNCTIONAL DESCRIPTION
PIN DESCRIPTIONS
The DDU222C-series device is a 5-tap digitally buffered delay line. The
IN 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
VDD +5 Volts
40, the total delay of the line is measured from T1 to T5, with the nominal
GND Ground
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 8.0ns. For dash numbers
greater than or equal to 40, the total delay of the line is measured from IN to T5, with the nominal value
given by the dash number. The nominDalattaapS-htoe-etat4pUd.ceolamy increment is given by 1/5 of this number.
