3D3314
APPLICATION NOTES (CONT’D)
The programmed delay accuracy of the device is
guaranteed, therefore, only for the user specified
input characteristics. Small input pulse width
variation about the selected pulse width will only
marginally impact the programmed delay
accuracy, if at all. Nevertheless, it is strongly
recommended that the engineering staff at
DATA DELAY DEVICES be consulted.
POWER SUPPLY AND
TEMPERATURE CONSIDERATIONS
The delay of CMOS integrated circuits is strongly
dependent on power supply and temperature.
The monolithic 3D3314 delay line utilizes novel
and innovative compensation circuitry to
minimize the delay variations induced by
fluctuations in power supply and/or temperature.
The thermal coefficient is reduced to 200 PPM/C,
which is equivalent to a variation, over the 0C-
70C operating range, of ±1% or 0.25ns
(whichever is greater) from the 25C delay
settings. The power supply coefficient is reduced,
over the 3.0V-3.6V operating range, to ±1% or
1ns (whichever is greater) of the delay settings at
the nominal 3.3VDC power supply.
It is essential that the power supply pin be
adequately bypassed and filtered. In addition,
the power bus should be of as low an
impedance construction as possible. Power
planes are preferred.
