FUNCTIONAL DESCRIPTION
IN
Signal Input
The DDU11H-series device is a 5-tap digitally buffered delay line. The
T1-T5
Tap Outputs
signal input (IN) is reproduced at the outputs (T1-T5), shifted in time by an
VEE
-5 Volts
amount determined by the device dash number (See Table). For dash
GND Ground
numbers less than 10, the total delay of the line is measured from T1 to
T5. The nominal tap-to-tap delay increment is given by one-fourth of the
total delay, and the inherent delay from IN to T1 is nominally 1.5ns. For dash numbers greater than or
equal to 10, the total delay of the line is measured from IN to T5. The nominal tap-to-tap delay increment
is given by one-fifth of this number.

APPLICATION NOTES
Delay Devices if your application requires device
testing at a specific input condition.
HIGH FREQUENCY RESPONSE
The DDU11H 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 20% of the total delay and periods as
small as 40% of the total delay (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
POWER SUPPLY BYPASSING
The DDU11H relies on a stable power supply to
produce repeatable delays within the stated
tolerances. A 0.1uf capacitor from VEE to GND,
located as close as possible to the VEE pin, is
recommended. A wide VEE trace and a clean
ground plane should be used.
