CERAMIC RESONATORS
Murata Electronics CERALOCK resonators have been tested with the ST92150-Auto at 3, 3.68, 4 and 5
MHz. These recommended resonators have built-in capacitors (see
The test circuit is shown in
Figure 69. Test Circuit
Table 32
Table 32. Obtained Results
Advantages of using ceramic resonators:
CSTCR and CSTCC types have built-in loading
capacitors.
Smallest loading capacitor resonators are recom-
mended for standard applications.
Highest loading capacitor resonators are recom-
mended for automotive applications with CAN and
tight frequency tolerance.
Test conditions:
The evaluation conditions are 4.5 to 5.5 V for the
supply voltage and -40° to 105° C for the tempera-
ture range.
Caution:
These circuit conditions are for design reference
only.
Recommended C1, C2 value depends on the cir-
cuit board used.

For tight frequency tolerance applications, please
contact the nearest Murata office for more de-
tailled PCB evaluation regarding layout.
Note 1:
Attention must be paid to leakage currents around
the OSCIN pin. Leakage paths from V
ter the DC polarization of the inverter stage and in-
troduce a mismatch with the second stage, and
possibly stop the clock signal. It is recommended
to surround the oscillator components by a ground
ring on the printed circuit board and if necessary to
apply a coating film to avoid humidity problems.
Note 2:
Attention must be paid to the capacitive loading of
OSCOUT. OSCOUT must not be used to drive ex-
ternal circuits.
