1503/1503j mechanically variable delay line (series 1503 & 1503j) d a ta delay devices, i n c. ? 3 features packages ? ideal for ?set and forget? applications ? multi-turn adjustment screw (1503: 40 turns, 1503j: 60 turns) ? stackable for pc board economy ? 20mil x 10mil flat leads (1503) ? #20 gauge leads (1503j) ? resolution: as low as 0.12ns ? dielectric breakdow n: 50 vdc ? temperature coefficient: 100 ppm/ c functional description the 1503- and 1503j-series devices are me chanically variable, passive delay lines. the signal input (in) is reproduced at the tap output (tap), shifted by an amount which can be adjusted between 0 and t d , where t d is the device dash number. the fixed output (out) r eproduces the input, delayed by t d , and must be terminated to match the characte ristic impedance of the line, which is given by the letter code that follows the dash number (see table). the tap output is unbuffered. the 3db bandwidth of the line is given by 0.35 / t r , where t r is the rise time of the line (see table). 150 3 gnd in o u t ta p 15 03- x x z 15 03j-x x z xx = m a x d e l a y ( t d ) z = im pe dan ce code 1 503j gnd i n ou t t ap pin descriptions in signal input tap variable output out fixed output gnd ground series specifications f u n ct i o n a l di ag ram gnd in ta p out . 500 1.310 m a x . . 312 . 020 p a ck ag . 010 e di me n s i o n s - 15 03 . 020 . 170 .187 . 375 1.000 . 150 . 300 . 100 . 100 . 100 1 2 in gn d 3 4 t ap ou t . 150 dash number specifications part number m ax dly (ns) tr (ns) i m ped ( ? ) rdc ( ? ) 1 5 0 3 - 1 5 a 1 5 3 5 0 0 . 7 1 5 0 3 - 2 5 a 2 5 5 5 0 0 . 8 1 5 0 3 - 3 0 a 3 0 6 5 0 1 . 0 1 5 0 3 - 4 0 a 4 0 8 5 0 1 . 5 1 5 0 3 - 5 0 a 5 0 1 0 5 0 1 . 7 1 5 0 3 - 6 0 a 6 0 1 2 5 0 2 . 0 1 5 0 3 - 8 0 a 8 0 1 6 5 0 3 . 0 1 5 0 3 - 1 0 0 a 1 0 0 2 0 5 0 3 . 5 1 5 0 3 - 1 5 b 1 5 3 1 0 0 1 . 0 1 5 0 3 - 3 0 b 3 0 6 1 0 0 2 . 0 1 5 0 3 - 5 0 b 5 0 1 0 1 0 0 3 . 0 1 5 0 3 - 6 0 b 6 0 1 2 1 0 0 4 . 0 1 5 0 3 - 8 0 b 8 0 1 6 1 0 0 5 . 0 1 5 0 3 - 1 0 0 b 1 0 0 2 0 1 0 0 1 4 . 0 1 5 0 3 - 1 2 0 b 1 2 0 2 4 1 0 0 8 . 0 1 5 0 3 - 1 4 0 b 1 4 0 2 8 1 0 0 1 4 . 0 1 5 0 3 - 1 6 0 b 1 6 0 3 2 1 0 0 1 0 . 0 1 5 0 3 - 2 0 0 b 2 0 0 4 0 1 0 0 1 4 . 0 1 5 0 3 - 3 0 c 3 0 6 2 0 0 4 . 0 1 5 0 3 - 6 0 c 6 0 1 2 2 0 0 9 . 5 1 5 0 3 - 1 0 0 c 1 0 0 2 0 2 0 0 1 4 . 0 1 5 0 3 - 2 0 d 2 0 4 2 5 0 5 . 0 1 5 0 3 - 2 0 e 2 0 4 3 0 0 5 . 0 1 5 0 3 - 3 0 f 3 0 6 3 5 0 8 . 0 1 5 0 3 - 2 5 g 2 5 5 4 0 0 8 . 0 1 5 0 3 - 4 0 h 4 0 8 5 0 0 1 2 . 0 1 5 0 3 j - 1 5 0 a 1 5 0 2 2 5 0 5 . 0 1 5 0 3 j - 2 5 0 b 2 5 0 3 8 1 0 0 2 1 . 0 1 5 0 3 j - 1 3 0 c 1 3 0 2 0 2 0 0 2 1 . 0 1 5 0 3 j - 3 0 d 3 0 5 2 5 0 7 . 0 1 5 0 3 j - 3 0 e 3 0 5 3 0 0 7 . 0 1 5 0 3 j - 4 0 f 4 0 6 3 5 0 1 0 . 0 1 5 0 3 j - 3 5 g 3 5 6 4 0 0 1 0 . 0 1 5 0 3 j - 6 0 h 6 0 9 5 0 0 1 8 . 0 ? 2004 data delay dev i ces doc #01011 data delay devices, inc. 1 8/23/04 3 mt. prospect ave. clifton, nj 07013
