TMP92CH21
4.5 Recommended Oscillation Circuit
The TMP92CH21 has been evaluated by the oscillator vender below. Use this information
when selecting external parts.
Note:
The total load value of the oscillator is the sum of external loads (C1 and C2) and the
floating load of the actual assembled board. There is a possibility of operating error
when using C1 and C2 values in the table below. When designing the board, design
the minimum length pattern around the oscillator. We also recommend that oscillator
evaluation be carried out using the actual board.
