APPLICATION NOTES (CONT’D)
custom reference designator identifying the
intended frequency and duty cycle of operation.
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 3D7304 programmable 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% from the
room-temperature delay settings and/or 0.5ns,
whichever is greater. The power supply
coefficient is reduced, over the 4.75V-5.25V
operating range, to
±1% of the delay settings at
the nominal 5.0VDC power supply and/or 1.0ns,
whichever is greater. 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.
