On-Chip Oscillators
The on-chip oscillator circuitry of the IS80C51/31 is a single
stage linear inverter, intended for use as a crystal-controlled,
positive reactance oscillator (Figure 21). In this application
the crystal is operated in its fundamental response mode as
an inductive reactance in parallel resonance with
capacitance external to the crystal (Figure 24). Examples
of how to drive the clock with external oscillator are shown
in Figure 22.
Figure 21. Oscillator Connections
The crystal specifications and capacitance values (C1 and
C2 in Figure 21) are not critical. 20 pF to 30 pF can be used
in these positions at a12 MHz to 24 MHz frequency with
good quality crystals. (For ranges greater than 24 MHz
refer to Figure 23.) A ceramic resonator can be used in
place of the crystal in cost-sensitive applications. When a
ceramic resonator is used, C1 and C2 are normally selected
to be of somewhat higher values. The manufacturer of the
ceramic resonator should be consulted for recommendation
on the values of these capacitors.
