FUNCTIONAL DESCRIPTION
The 1509- and 1509J-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).

PASSIVE DELAY LINE TEST SPECIFICATIONS
TEST CONDITIONS
INPUT: OUTPUT:
Ambient Temperature: 25oC ± 3oC Rload: 10MΩ
Input Pulse: High = 3.0V typical Cload: 10pf
Low = 0.0V typical Threshold: 50% (Rising & Falling)
Source Impedance: 50Ω Max.
Rise/Fall Time: 3.0 ns Max. (measured
at 10% and 90% levels)
Pulse Width (TD <= 75ns): PWIN = 100ns
Period (TD <= 75ns): PERIN = 1000ns
Pulse Width (TD > 75ns): PWIN = 2 x TD
Period (TD > 75ns): PERIN = 10 x TD
NOTE: The above conditions are for test only and do not in any way restrict the operation of the device.
