FUNCTIONAL DESCRIPTION
PIN DESCRIPTIONS
The DDU12H-series device is a 10-tap digitally buffered delay line. The
IN
Signal Input
signal input (IN) is reproduced at the outputs (T1-T10), shifted in time by
T1-T10 Tap Outputs
an amount determined by the device dash number (See Table). For dash
VEE
-5 Volts
numbers less than 20, the total delay of the line is measured from T1 to
GND Ground
T10. The nominal tap-to-tap delay increment is given by one-ninth of the
total delay, and the inherent delay from IN to T1 is nominally 1.5ns. For dash numbers greater than or
equal to 20, the total delay of the line is measured from IN to T10. The nominal tap-to-tap delay increment
is given by one-tenth of this number.

APPLICATION NOTES
Delay Devices if your application requires device
testing at a specific input condition.
HIGH FREQUENCY RESPONSE
The DDU12H 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 10% of the total delay and periods as
small as 20% 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 DDU12H 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.
