• Set Ro to the median impedance value within
the delay adjustment range (50Ω - 60Ω)

ECL without –2V Termination
Note: The varicap voltage is referenced to the DC level of the input signal. 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.
