Table 1 Ceramic Oscillator Guaranteed Constants

Oscillator type

508-kHz ceramic oscillator

Manufacturer

Oscillator element

Murata Mfg. Co., Ltd.

CSB 508E

C1

150 pF

C2

150 pF

Note: Capacitors with K tolerance (±10%) and SL characteristics must be used for C1 and C2.

· Since this circuit is influenced by the length of the circuit pattern, components related to oscillator functioning must be mounted as close together as

possible so that pattern lines do not become longer than is absolutely necessary.

· The characteristics are not guaranteed if an oscillator element other than the one listed above is used.
