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.

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. 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.
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 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

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.

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.
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
