MECHANICALLY VARIABLE DELAY LINE

1503/1503J MECHANICALLY VARIABLE DELAY LINE (SERIES 1503 & 1503J) data delay devices, inc. ? 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 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 T D , where T D is the device dash number. The fixed output (OUT) reproduces the input, delayed by T D , 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
