FUNCTIONAL DESCRIPTION
The MDU13H-series device is a 3-in-1 digitally buffered delay line. The
signal inputs (I1-I3) are reproduced at the outputs (O1-O3), shifted in time
by an amount determined by the device dash number (See Table). The
delay lines function completely independently of each other.

APPLICATION NOTES
HIGH FREQUENCY RESPONSE
The MDU13H 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 50% of the total delay and periods as
small as 100% 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

Delay Devices if your application requires device
testing at a specific input condition.
POWER SUPPLY BYPASSING
The MDU13H 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.
