FUNCTIONAL DESCRIPTION
The 3D3314 device is a small, versatile, quad fixed monolithic delay line.
Delay values ranging from 10ns through 400ns may be specified via the
device dash number. Each input is reproduced at the corresponding
output without inversion, shifted in time as per user selection. The
3D3314 is 3.3V CMOS-compatible and features both rising- and falling-
edge accuracy. The device is offered in a standard 14-pin auto-insertable
DIP and a space saving surface mount 14-pin SOIC.

APPLICATION NOTES
OPERATIONAL DESCRIPTION
The 3D3314 quad fixed delay line architecture is
shown in Figure 1. Each delay line is composed
of a number of delay cells connected in series.
Each delay line produces at its output a replica of
the signal present at its input, shifted in time. The
delay lines are matched and share the same
compensation signals, which minimizes line-to-
line delay deviations over temperature and
supply voltage variations.
Table 1 delay accuracy for input frequencies
higher than the Recommended Maximum
Frequency, the 3D3314 must be tested at the
user operating frequency. Therefore, to facilitate
production and device identification, the part
number will include a custom reference
designator identifying the intended frequency of
operation. The programmed delay accuracy of
the device is guaranteed, therefore, only at the
user specified input frequency. Small input
frequency variation about the selected frequency
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.
INPUT SIGNAL CHARACTERISTICS
The Frequency and/or Pulse Width (high or low)
of operation may adversely impact the specified
delay accuracy of the particular device. The
reasons for the dependency of the output delay
accuracy on the input signal characteristics are
varied and complex. Therefore a
Recommended
Maximum
and an
Absolute Maximum
operating
input frequency and a
Recommended Minimum
and an
Absolute Minimum
operating pulse
width have been specified.
OPERATING PULSE WIDTH
The
Absolute Minimum Pulse Width
(high or
low) specification, tabulated in Table 1,
determines the smallest Pulse Width of the delay
line input signal that can be reproduced, shifted
in time at the device output, with acceptable
pulse width distortion.
The
Recommended Minimum Pulse Width
(high or low) specification determines the
smallest Pulse Width of the delay line input signal
for which the output delay accuracy tabulated in
Table 1 is guaranteed.
To guarantee the Table 1 delay accuracy for
input pulse width smaller than the Recommended
Minimum Pulse Width, the 3D3314 must be
tested at the user operating pulse width.
Therefore, to facilitate production and device
identification, the part number will include a
custom reference designator identifying the

OPERATING FREQUENCY
The
Absolute Maximum Frequency
specification, tabulated in Table 1, determines
the highest frequency of the delay line input
signal that can be reproduced, shifted in time at
the device output, with acceptable duty cycle
distortion.
The
Recommended Maximum Frequency
specification determines the highest frequency of
the delay line input signal for which the output
delay accuracy is guaranteed. To guarantee the

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.

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
