FUNCTIONAL DESCRIPTION
PIN DESCRIPTIONS
The DLO31F-series device is a gated delay line oscillator. The device
produces a stable square wave which is synchronized with the falling edge
of the Gate Input (GB). The frequency of oscillation is given by the device
dash number (See Table). The two outputs (C1,C2) are in phase during
oscillation, but return to opposite logic levels when the device is disabled.

APPLICATION NOTES
THERMAL STABILITY
POWER SUPPLY BYPASSING
The delay line used internally to develop the clock
signals in the DLO31F has a thermal coefficient
of 100ppm/C. For low frequency units, this is also
the thermal coefficient of the output frequency.
For higher frequency units, however, other
internal effects must be considered, and the
actual thermal coefficient may be somewhat
higher.
The DLO31F relies on a stable power supply to
produce a repeatable frequency 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.
