Recommended Oscillator Circuits
The oscillator circuit, a Pierce oscillator, is designed to work with both, an external crystal
oscillator or an external stable clock source. It basically consists of an inverting amplifier
and a feedback element with XTAL1 as input, and XTAL2 as output.
When using a crystal, a proper external oscillator circuitry must be connected to both
pins, XTAL1 and XTAL2. The crystal frequency can be within the range of 4 MHz
to 25 MHz. Additionally, it is necessary to have two load capacitances
C
X1 and CX2, and
depending on the crystal type, a series resistor
R
X2, to limit the current. A test resistor RQ
may be temporarily inserted to measure the oscillation allowance (negative resistance)
of the oscillator circuitry.
R
Q values are typically specified by the crystal vendor. The CX1
and
C
X2 values shown in Figure 3-15 can be used as starting points for the negative
resistance evaluation and for non-productive systems. The exact values and related
operating range are dependent on the crystal frequency and have to be determined and
optimized together with the crystal vendor using the negative resistance method.
