1 / 4 page DDU224F Doc #97015 DATA DELAY DEVICES, INC. 1 1/29/97 3 Mt. Prospect Ave. Clifton, NJ 07013 10-TAP, TTL-INTERFACED FIXED DELAY LINE (SERIES DDU224F) FEATURES PACKAGES • Ten 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 DDU224F-series device is a 10-tap digitally buffered delay line. The signal input (IN) is reproduced at the outputs (T1-T10), shifted in time by an amount determined by the device dash number. The nominal tap-to- tap delay increment is given by 1/10 of the dash number. For dash numbers less than 50, the total delay of the line is measured from T1 to T10, with the nominal value given by 9 times the increment. The inherent delay from IN to T1 is nominally 3.5ns. For dash numbers greater than or equal to 50, the total delay of the line is measured from IN to T10, with the nominal value given by the dash number.
