FUNCTIONAL DESCRIPTION
PIN DESCRIPTIONS
The DDU8C-series device is a 5-tap digitally buffered delay line. The
signal input (IN) is reproduced at the outputs (T1-T5), shifted in time by an
amount determined by the device dash number (See Table). 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 the total delay.

APPLICATION NOTES
Delay Devices if your application requires device
testing at a specific input condition.
HIGH FREQUENCY RESPONSE
The DDU8C 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 40% of the total delay and periods as
small as 80% 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 DDU8C relies on a stable power supply to
produce repeatable delays within the stated
tolerances. A 0.1uf capacitor from VDD to GND,
located as close as possible to the VDD pin, is
recommended. A wide VDD trace and a clean
ground plane should be used.
