CXD2931R-9/GA-9
Application Notes
The constants shown in the circuits below are the examples, and do not quarantee the circuit operation.
1. TCXO input
(1) When inputting the binary-converted signal
The TCXO (Pin 7) input signal should be 18.414MHz ± 3ppm.
(2) When performing the self-oscillation with the TCXO and XTCXO pins (Pins 7 and 8)
The TCXO (Pin 7) input signal should be 18.414MHz ± 3ppm.
2. CPU clock generation
Pin 32 is used to select that TCXO is used or that the self-oscillation is performed with the MCKI and
MCKO pins (Pins 30 and 31).
(1) TCXO solution (TCXO is used for CPU clock)
Set Pin 32 to low.
Pin 30: Low
Pin 31: Open
(2) When performing the self-oscillation with the MCKI and MCKO pins (Pins 30 and 31)
Set Pin 32 to high.
The crystal frequency should be less than 20MHz.
The following circuit is just a reference, and is not guaranteed.
