PACKAGES 1 2 3 4 5 6 7 8 VCC IN T1 T2 T3 T4 T5 GND DDU222F-xx Commercial DDU222F-xxM Military FUNCTIONAL DESCRIPTION PIN DESCRIPTIONS The DDU222F-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 VCC +5 Volts 25, 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 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.
