ST90158 - RESET AND CLOCK CONTROL UNIT (RCCU)
OSCILLATOR CHARACTERISTICS (Cont’d)
CERAMIC RESONATORS
Murata Electronics CERALOCK resonators have been tested with the ST90158 at 3, 3.68, 4 and 5 MHz.
Some resonators have built-in capacitors (see Table 18).
The test circuit is shown in Figure 40.
Figure 40. Test circuit
Table 18 shows the recommended conditions at different frequencies.
Table 18. Obtained Results
Advantages of using ceramic resonators:
CST and CSTCC types have built-in loading ca-
pacitors (those with values shown in parentheses
()).
Rp is always open in the previous table because
there is no need for a parallel resistor with a reso-
nator (it is needed only with a crystal).
Test conditions:
The evaluation conditions are 2.7 to 5.5 V for the
supply voltage and -40
° to 85° C for the tempera-
ture range.
Caution:
The above circuit condition is for design reference
only.
Recommended C1, C2 value depends on the cir-
cuit board used.
