1-2 Setting Up TIN
1) Setting Up the Level
The TIN terminal is shown in Fig.a. In order for the level of TIN to satisfy the conditions shown in
the table below, the external circuits shown in Fig.b or Fig.c should be used when the external
voltage level of the input is high.

2) Setting Up frequency
The periodical change of TIN is expected to be +30% ~ -20%. The fIN is set to
approximately 1.5 times fOSC
fIN = 1.5 * fOSC
