(SERIES 1503 & 1503J) data delay devices, inc.

FEATURES

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 breakdown:

50 Vdc

Temperature coefficient: 100 PPM/°C FUNCTIONAL DESCRIPTION The 1503- and 1503J-series devices are mechanically 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 TD, where TD is the device dash number. The fixed output (OUT) reproduces the input, delayed by TD, and must be terminated to match the characteristic 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 / TR, where TR is the rise time of the line (See Table). 1503 GND IN OUT TAP 1503-xxz 1503J-xxz xx = Max Delay (TD) z = Impedance Code 1503J GND IN OUT TAP PIN DESCRIPTIONS IN Signal Input TAP Variable Output OUT Fixed Output GND Ground SERIES SPECIFICATIONS Functional Diagram GND IN TAP OUT .500 1.310 MAX. .312 .020 Packag .010 e Dimensions - 1503 .020 .170 .187 .375 1.000 .150 .300 .100 .100 .100 IN GND TAP OUT .150 DASH NUMBER SPECIFICATIONS Part Number Max Dly (ns) TR (ns) Imped (Ω) RDC (Ω) 1503-15A 0.7 1503-25A 0.8 1503-30A 1.0 1503-40A 1.5 1503-50A 1.7 1503-60A 2.0 1503-80A 3.0 1503-100A 100 3.5 1503-15B 100 1.0 1503-30B 100 2.0 1503-50B 100 3.0 1503-60B 100 4.0 1503-80B 100 5.0 1503-100B 100 100 14.0 1503-120B 120 100 8.0 1503-140B 140 100 14.0 1503-160B 160 100 10.0 1503-200B 200 100 14.0 1503-30C 200 4.0 1503-60C 200 9.5 1503-100C 100 200 14.0 1503-20D 250 5.0 1503-20E 300 5.0 1503-30F 350 8.0 1503-25G 400 8.0 1503-40H 500 12.0 1503J-150A 150 5.0 1503J-250B 250 100 21.0 1503J-130C 130 200 21.0 1503J-30D 250 7.0 1503J-30E 300 7.0 1503J-40F 350 10.0 1503J-35G 400 10.0 1503J-60H 500 18.0 2004 Data Delay Devices Doc #01011 DATA DELAY DEVICES, INC. 8/23/04 3 Mt.
