APPLICATION NOTES
HIGH FREQUENCY RESPONSE
The DDU47F 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 10ns and periods as small 20ns (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 DDU47F relies on a stable power supply to
produce repeatable delays within the stated
tolerances. A 0.1uf capacitor from VCC to GND,
located as close as possible to the VCC pin, is
recommended. A wide VCC trace and a clean
ground plane should be used.
