60. Optimize the circuit constant for each product when you use this oscillation cell and ask to the manufacturer of the crystal oscillator to

investigate (matching investigation) because the best circuit constant changes depending on the specification of the crystal oscillator used

and the ambient surrounding (parasitic capacitance etc. of an external substrate).

61. The values of parts are for reference. There is a possibility that the adjustment is needed according to the situation of the set.

62. The following may be needed as the anti−noise measures of oscillation circuit.

− Be adjacent as much as possible, and shorten wiring between elements such as this LSI and the crystal oscillator.

− GND of the oscillation circuit close to GND (VSS) of this LSI as much as possible.

− Do not bring the wiring pattern of the large current drive close around the oscillation circuit.

− Take wide pattern to avoid the effect of interference of other signals.
