3 ^{Specifications of CERALOCK®}
1. Electrical Specifications
The frequency stability of CERALOCK^® is between that
of crystal and LC or RC oscillators. Temperature
stability is ±0.3 to ±0.5% against initial values within
-20 to +80°C. The initial frequency precision is
±0.5% for standard products. The frequency of the
standard CERALOCK^® is adjusted by the standard
measuring circuit, but the oscillation frequency may
shift when used in the actual IC circuit. Usually, if the
frequency precision needed for clock signal of a 1 chip
3
microcomputer is approximately ±2 to 3% under
working conditions, CERALOCK^® standard type can be
used in most cases. If exact oscillation frequency is
required for a special purpose, Murata can manufacture
the ceramic resonator for the desired frequency.
The following are the general electrical specifications of
CERALOCK^®. (As for the standard measuring circuit of
oscillation frequency, please refer to the next chapter
“Application to Typical Oscillation Circuits”.)
Electrical Specifications of MHz Band Lead
CERALOCK^® (CSTLS Series)
Electrical specifications of CSTLS series are shown in
the tables. Please note that oscillation frequency
measuring circuit constants of the CSTLS ˘G56 series
(with H-CMOS IC) depends on frequency.

MHz band three-terminal CERALOCK^® (CSTLS Series)
is built-in load capacitance.
Fig. 3-1 shows the electrical equivalent circuit.
The table shows the general specifications of the CSTLS
series. Input and output terminals of the three-terminal
CERALOCK^® are shown in the table titled Dimensions
of CERALOCK^® CSTLS series in Chapter 1 on page 6.
But connecting reverse, the oscillating characteristics
are not affected except that the frequency has a slight
lag.
