2. Setting up TIN
1) Setting up the level
The TIN terminal is shown in Figure a. In order for the level of TIN to satisfy the conditions shown in the table below,
the external circuits shown in Figure b or Figure 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% to −20%. The fIN is set to approximately 1.5 times fOSC.
fIN = 1.5 • fosc
