FUNCTIONAL DESCRIPTION
PIN DESCRIPTIONS
The PDU1016H-series device is a 4-bit digitally programmable delay line.
The delay, TDA, from the input pin (IN) to the output pin (OUT) depends on
the address code (A3-A0) according to the following formula:
IN
Signal Input
OUT Signal Output
A0-A3 Address Bits
ENB Output Enable
VEE -5 Volts
TDA = TD0 + TINC * A
GND Ground
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 specified by the dash number of the
device and can range from 0.5ns through 100ns, inclusively. The enable pin (ENB) is held LOW during
normal operation. When this signal is brought HIGH, OUT is forced into a LOW state. The address is not
latched and must remain asserted during normal operation.

APPLICATION NOTES
spurious signals persists until the required TDISH
has elapsed.
ADDRESS UPDATE
The PDU1016H 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 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.
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:
,
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 ENB
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 ENB 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
