APPLICATION NOTES
*HIGH FREQUENCY RESPONSE
The DDU39F tolerances are guaranteed for input pulse widths and periods greater than those
specified in the test conditions.
Although the device will function properly for pulse widths as small as 10ns and periods as small 20ns (for a symmetric input), the delays may deviate from their values at low frequency.
However, for a given input condition, the deviation will be repeatable from pulse to pulse.
Contact technical support at Data Delay Devices if your application requires device testing at a specific input condition.
*POWER SUPPLY BYPASSING
The DDU39F relies on a stable power supply to produce repeatable delays within the stated
tolerances.
A 0.1uf capacitor from VCC to GND, located as close as possible to the VCC pin, is recommended.
A wide VCC trace and a clean ground plane should be used.

FUNCTIONAL DESCRIPTION
The 3D7521 is a monolithic CMOS Manchester Encoder.
The clock and data, present at the unit input, are combined into a single bi-phase-level signal. In this encoding mode, a logic one is represented by a high-to-low transition within the bit cell, while a logic zero is represented by a low-to-high transition.
The unit operating baud rate (in Mbaud) is equal to the input clock frequency (in MHZ).
All pins marked N/C must be left unconnected.
The all-CMOS 3D7521 integrated circuit has been designed as a reliable, economic alternative to hybrid TTL Manchester Encoder.
It is TTL- and CMOS-compatible, capable of driving ten 74LS-type loads.
It is offered in space saving surface mount 8-pin and 14-pin SOICs.
The 3D7521 Manchester Encoder samples the data input at the rising edge of the input clock.
The sampled data is used in conjunction with the clock rising and falling edges to generate the by-phase level Manchester code.
FEATURES
* All-silicon, low-power CMOS technology
* TTL/CMOS compatible inputs and outputs
* Vapor phase, IR and wave solderable
* Low ground bounce noise
* Maximum data rate: 50 MBaud
FUNCTIONAL DESCRIPTION
The 3D7522 product family consists of monolithic CMOS Manchester Decoders.
The unit accepts at the RX input a bi-phase-level, embedded-clock signal.
In this encoding mode, a logic one is represented by a high-to-low transition within the bit cell, while a logic zero is represented by a low-to-high transition.
The recovered clock and data signals are presented on CLK and DATB, respectively, with the data signal inverted.
The operating baud rate (in MBaud) is specified by the dash number.
The input baud rate may vary by as much as ±15% from the nominal device baud rate without compromising the integrity of the information received.
Because the 3D7522 is not PLL-based, it does not require a long preamble in order to lock onto the received signal.
Rather, the device requires at most one bit cell before the data presented at the output is valid.
This is extremely useful in cases where the information arrives in bursts and the input is otherwise turned off.
The all-CMOS 3D7522 integrated circuit has been designed as a reliable, economic alternative to hybrid TTL Manchester Decoders.
It is TTL- and CMOS-compatible, capable of driving ten 74LS-type loads.
It is offered in space saving surface mount 8-pin and 14-pin SOICs.

FUNCTIONAL DESCRIPTION
The 3D3220 10-Tap Delay Line product family consists of fixed-delay CMOS integrated circuits. Each package contains a single delay line, tapped and buffered at 10 points spaced uniformly in time. Tap-to-tap (incremental) delay values can range from 0.75ns through 700ns. The input is reproduced at the outputs without inversion, shifted in time as per the user-specified dash number.
The 3D3220 is TTL- and CMOS-compatible, capable of driving ten 74LS-type loads, and features both rising- and falling-edge accuracy. The all-CMOS 3D3220 integrated circuit has been designed as a reliable, economic alternative to hybrid TTL fixed delay lines. It is offered in a standard 14-pin auto-insertable DIP and space saving surface mount 14-pin SOIC and 16-pin SOL packages.
APPLICATION NOTES
OPERATIONAL DESCRIPTION The 3D3220 ten-tap delay line architecture is shown in Figure 1. The delay line is composed of a number of delay cells connected in series. Each delay cell produces at its output a replica of the signal present at its input, shifted in time. The delay cells are matched and share the same compensation signals, which minimizes tap-to-tap 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 3D3220 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 3D3220 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 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.
