General Description
MOTOROLA
1.7.2.2 2-Pin Ceramic Resonator Oscillator
In cost-sensitive applications, a ceramic resonator can be used instead
of the crystal. The circuit in Figure 1-3(a) is for a ceramic resonator also.
The resonator manufacturer’s recommendations should be followed,
since the resonator parameters determine the external component
values required for maximum stability and reliable starting. The load
capacitance values used in the oscillator circuit design should include all
stray capacitances. The ceramic resonator and components should be
mounted as close as possible to the pins for startup stabilization and to
minimize output distortion. An internal startup resistor of approximately
2 M
is provided between OSC1 and OSC2 for the crystal/ceramic
resonator oscillator mask option register bit.
1.7.2.3 2-Pin RC Oscillators
The 2-pin RC oscillator configuration can be used for very low-cost
applications. With this option, a resistor must be connected between the
two oscillator pins and a capacitor must be connected from the OSC1 pin
square wave and the signal on the OSC1 pin approximates a triangular
wave.
The 2-pin RC oscillator is selected by programming bit 5 ("RC") of the
mask option register located at $0012. Bit 6 ("Pin 3") should NOT be
programmed when using the 2-pin oscillator.
The 2-pin RC oscillator is optimized for operation at 500 kHz. This
oscillator can be used at higher or lower frequencies with degraded
accuracy over temperature, supply voltage, and/or device processing
variations. The internal startup resistor of approximately 2 M
is not
connected between OSC1 and OSC2 when the 2-pin RC oscillator mask
option register bit is selected.
