FUNCTIONAL DESCRIPTION
PIN DESCRIPTIONS
The PDU18F-series device is a 8-bit digitally programmable delay line.

depends on the address code (A7-A0) according to the following formula:
TDA = TD0 + TINC * A
where A is the address code, TINC is the incremental delay of the device,
and TD0 is the inherent delay of the device. The incremental delay is
GND Ground
specified by the dash number of the device and can range from 0.5ns through 10ns, inclusively. The
enable pins (EN/) are held LOW during normal operation. These pins must always be in the same state
and may be tied together externally. When these signals are brought HIGH, OUT and OUT/ are forced into
LOW and HIGH states, respectively. The address is not latched and must remain asserted during normal
operation.

APPLICATION NOTES
spurious signals persists until the required TDISH
ADDRESS UPDATE
has elapsed.
The PDU18F is a memory device. As such,
special precautions must be taken when
changing the delay address in order to prevent
spurious output signals. The timing restrictions
are shown in Figure 1.
INPUT RESTRICTIONS
There are three types of restrictions on input
pulse width and period listed in the AC
Characteristics table. The recommended
conditions are those for which the delay
After the last signal edge to be delayed has
appeared on the OUT pin, a minimum time, TOAX
is required before the address lines can change.
This time is given by the following relation:
,
tolerance specifications and monotonicity are
guaranteed. The suggested conditions are
those for which signals will propagate through the
unit without significant distortion. The absolute
conditions are those for which the unit will
produce some type of output for a given input.
TOAX = max { (Ai - A i-1) * TINC , 0 }
where A i-1 and Ai are the old and new address
codes, respectively. Violation of this constraint
When operating the unit between the
may, depending on the history of the input signal,
cause spurious signals to appear on the OUT
pin. The possibility of spurious signals persists
until the required TOAX has elapsed.
recommended and absolute conditions, the
delays may deviate from their values at low
frequency. However, these deviations will
remain constant from pulse to pulse if the input
pulse width and period remain fixed. In other
words, the delay of the unit exhibits frequency
and pulse width dependence when operated
beyond the recommended conditions. Please
consult the technical staff at Data Delay Devices
if your application has specific high-frequency
requirements.
A similar situation occurs when using the EN/
signal to disable the output while IN is active. In
this case, the unit must be held in the disabled
state until the device is able to “clear” itself. This
is achieved by holding the EN/ signal high and
the IN signal low for a time given by:
TDISH = Ai * TINC
Please note that the increment tolerances listed
represent a design goal. Although most delay
increments will fall within tolerance, they are not
guaranteed throughout the address range of the
unit. Monotonicity is, however, guaranteed over
all addresses.
Violation of this constraint may, depending on the
history of the input signal, cause spurious signals
to appear on the OUT pin. The possibility of
