VDJ Ultra High-Speed Variable Delay Lines

The VDJ type (VDJ1010) of dual in-line variable delay lines is available in one standard device or to your custom specifications.

Features

High-speed variable delay line that allows broad usage with such ultra-high-speed logic elements as the ECLinPS.
Also suitable for use in a broad range of applications in analog circuits. The part is in a miniaturized, hermetically sealed package that can be easily washed.

DC Max Voltage	DC 3V max. constantly
-3dB Passband:	1GHz or more
Inherent Delay:	230 ps max. at the minimum point within the variable range
Waveform Distortion:	Overshoot/Preshoot under ±20%
Delay Time Temp. Coefficient	± 100ppm/°C
Operating Temperature Range:	-10°C to +80°C
Storage Temperature Range:	-40°C to +120°C
Switching Life Expectancy:	Guaranteed within 100 cycles. (One cycle is defined as the movement of the knob from one end to the other.)

Part Number	Delay Time Range ± 10%	Increment Resolution	Rise Time (20% - 80%)	Input Impedance	Output Impedance	Logic Family Preferred
