VOLTAGE-VARIABLE DELAY LINE TR < 1ns (SERIES 3010) FEATURES • • • • • • • PACKAGE Varactor Technology Fast rise time for high frequency applications Delay continuously adjustable from 2.4ns to 3.4ns Very narrow device (SIP package) Stackable for PC board economy Epoxy encapsulated Meets or exceeds MIL-D-23859C 3010 1 3 IN G 6 7 VC G 9 OUT 3010-P: Positive control voltage 3010-N: Negative control voltage FUNCTIONAL DESCRIPTION PIN DESCRIPTIONS The 3010-series devices are continuously variable, single-input, singleIN Signal Input output, passive delay lines. The signal input (IN) is reproduced at the OUT Signal Output output (OUT), shifted by a time (TD) which is adjusted via an applied VC Control Voltage control voltage (VC). This control voltage is positive for the 3010-P and G Ground negative for the 3010-N. The characteristic impedance of the line is nominally 50 ohms. The rise time (TR) of the lines is no more than 1ns, resulting in a 3dB bandwidth of at least 300MHz. The delay resolution is limited only by that of the control voltage.

In the case of ECL applications, a voltage of 0V to 10V (2.6V to 12.6V for the 3010-N) should be applied at pin 6, because the signal line has –1.3V DC level. This assumes the ECL signal has approximately 50% duty cycle. Doc #04001 1/19/04 DATA DELAY DEVICES, INC.
