As described in Chapter 2, the most common oscillation
circuit with CERALOCK
circuit with CERALOCK
varies with the application and the IC being used, etc.
Although the basic configuration of the circuit is the
same as that of a quartz crystal, the difference in
mechanical Q results in the difference of the circuit
constant.
This chapter briefly describes the characteristics of the
oscillation circuit and gives some typical examples.
It is becoming more common to configure the oscillation
circuit with a digital IC, and the simplest way is to use
an inverter gate.
Fig. 4-1 shows the configuration of a basic oscillation
circuit with a C-MOS inverter.
INV. 1 works as an inverter amplifier of the oscillation
circuit. INV. 2 acts to shape the waveform and also acts
as a buffer for the connection of a frequency counter.
The feedback resistance Rf provides negative feedback
around the inverter in order to put it in the linear
region, so the oscillation will start, when power is
applied.
If the value of Rf is too large, and if the insulation
resistance of the input inverter is accidentally
decreased, oscillation will stop due to the loss of loop
gain. Also, if Rf is too great, noise from other circuits
can be introduced into the oscillation circuit.
Obviously, if Rf is too small, loop gain will be low. An Rf
of 1MΩ is generally used with a ceramic resonator.
Damping resistor Rd provides loose coupling between
the inverter and the feedback circuit and decreases the
loading on the inverter, thus saving energy.
In addition, the damping resistor stabilizes the phase of
the feedback circuit and provides a means of reducing
the gain in the high frequency area, thus preventing the
possibility of spurious oscillation.
Load capacitance C
180°.
The proper selected value depends on the application,
the IC used, and the frequency.
