APPLICATION NOTES (CONT’D)
POWER SUPPLY AND
TEMPERATURE CONSIDERATIONS
The delay of CMOS integrated circuits is strongly
dependent on power supply and temperature.
The monolithic 3D3702 oscillator utilizes novel
and innovative compensation circuitry to
minimize the frequency variations induced by
fluctuations in power supply and/or temperature.
The thermal coefficient is reduced to 250 PPM/C,
which is equivalent to a variation, over the -40C
to 85C operating range, of ±1.5% from the room-
temperature frequency setting. The power supply
coefficient is reduced, over the 3.0V to 3.6V
operating range, to ±0.5% of the frequency
setting at the nominal 3.3VDC power supply.
These specifications hold for the lower
frequencies only. For higher dash numbers, the
variations will be slightly greater, as noted in
Table 1. It is essential that the power supply
pin be adequately bypassed and filtered. In
addition, the power bus should be of as low
an impedance construction as possible.
Power planes are preferred.
