| 1509/1509J MECHANICALLY VARIABLE DELAY LINE (SERIES 1509 & 1509J) FEATURES * * * * * * * * * Ideal for "Set and Forget" applications Multi-turn adjustment screw (1509: 20 turns, 1509J: 60 turns) Stackable for PC board economy Fits standard 14-pin DIP socket (1509) 20mil x 10mil flat leads (1509) #20 gauge leads (1509J) Resolution: As low as 0.15ns Dielectric breakdown: 50 Vdc Temperature coefficient: 200 PPM/C GND TAP data 3 delay devices, inc. PACKAGES 1509 OUT IN 1509J 1509-XXZ 1509J-xxz xx = Max Delay (TD) z = Impedance Code GND IN OUT TAP FUNCTIONAL DESCRIPTION PIN DESCRIPTIONS The 1509- and 1509J-series devices are mechanically variable, passive delay IN Signal Input lines. The signal input (IN) is reproduced at the tap output (TAP), shifted by an TAP Variable Output amount which can be adjusted between 0 and TD, where TD is the device dash OUT Fixed Output number. The fixed output (OUT) reproduces the input, delayed by TD, and GND Ground 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).
