1 / 4 page DDU222F Doc #97011 DATA DELAY DEVICES, INC. 1 1/27/97 3 Mt. Prospect Ave. Clifton, NJ 07013 5-TAP, TTL-INTERFACED FIXED DELAY LINE (SERIES DDU222F) FEATURES PACKAGES • Five equally spaced outputs • Very narrow device (SIP package) • Stackable for PC board economy • Input & outputs fully TTL interfaced & buffered • 10 T 2L fan-out capability FUNCTIONAL DESCRIPTION The DDU222F-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.
