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:

TD_A= TD₀+ T_INC* A

where A is the address code, T_INCis the incremental delay of the device,

and TD₀is 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 T_DISH

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, T_OAX

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.

T_OAX= max { (A_i- A _i-1) * T_INC, 0 }

where A _i-1and A_iare 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 T_OAXhas 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:

T_DISH= A_i* T_INC

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
