FUNCTIONAL DESCRIPTION
The 3D3323 Triple Delay Line product family consists of fixed-delay
CMOS integrated circuits. Each package contains three matched,
independent delay lines. Delay values can range from 10ns through
6000ns. The input is reproduced at the output without inversion,
shifted in time as per the user-specified dash number. The 3D3323
is CMOS-compatible and features both rising- and falling-edge
accuracy.
The all-CMOS 3D3323 integrated circuit has been designed as a
reliable, economic alternative to hybrid fixed delay lines. It is offered
in a standard 8-pin auto-insertable DIP and a space saving surface mount 8-pin SOIC.

APPLICATION NOTES
OPERATIONAL DESCRIPTION
The 3D3323 triple delay line architecture is
shown in Figure 1. The individual delay lines are
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.
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 Maximum and
an Absolute Maximum operating input
frequency and a Minimum and an Absolute
Minimum operating pulse width have been
specified.
OPERATING FREQUENCY
The Absolute Maximum Operating 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 Maximum Operating Frequency
specification determines the highest frequency of
the delay line input signal for which the output
delay accuracy is guaranteed.
To guarantee the Table 1 delay accuracy for
input frequencies higher than the Maximum
Operating Frequency, the 3D3323 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.
OPERATING PULSE WIDTH
The Absolute Minimum Operating 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 Minimum Operating 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 Minimum
Operating Pulse Width, the 3D3323 must be
tested at the user operating pulse width.
Therefore, to facilitate production and device
identification, the part number will include a

variation about the selected pulse width will only

accuracy, if at all. Nevertheless, it is strongly

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 3D3323 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 300
PPM/C, which is equivalent to a variation , over
the -40C to 85C operating range, of ±3% from
the room-temperature delay settings and/or
1.0ns, whichever is greater. The power supply
coefficient is reduced, over the 3.0V to 3.6V
operating range, to ±1% of the delay settings at
the nominal 3.3VDC power supply and/or 2.0ns,
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.
