The oscillation circuit characteristics may differ by applications. For further assistance, please contact with the oscillator manufacturer with the following notes in your mind. * Since the oscillation frequency precision is affected by wiring capacity of the application board, etc., adjust the oscillation frequency on the production board. Since the oscillation circuit characteristics are affected by the noise, wiring capacity, etc., refer to the following notices. * The distance between the clock I/O terminal and external parts should be as short as possible. * The capacitors' VSS should be allocated close to the microcontroller's GND terminal and be away from other GND. * The signal lines with rapid state changes or the signal line with large amplitude such as middle withstand voltage port or LCD driver output should be allocated away from the clock oscillation circuit. * The signal lines with large current should be allocated away from the oscillation circuit. 11/14 LC573706A XT1 XT2 X'tal C1 Figure 1 C2 Crystal Oscillation Circuit VSS VDD3 CUP1 1 CUP2 Figure 2 XT1 XT2 DUT C1 C2 VDD2 VDC VDD1 Current Dissipation Measurement Circuit/VDD1 and VDD3 Terminals Output Voltage Measurement Circuit Note: The specification above indicates the operational characteristics of a die that has been packaged by SANYO into a QIC80 package.
