Universal PCB Design for any of YMU759, YMU759B, and YMU759C
As far as lower voltage (1.8V) CPU interface of YMU759C (MA-2L) is not used, you can mount any of YMU759,
YMU759B, or YMU759C on the same PCB design by designing PCB board as below.

- Pin#7 and Pin#32 shall be connected
- Set Pin#5 to “High” level
YMU759C only supports parallel CPU bus interface. To have universal PCB design, YMU759/B/C must be set to Parallel
Interface mode by setting Pin#5 to “High”.
Moreover, don’t use TCXO for CLKI clock input because YMU759 and YMU759B don’t support it.
<Reference>
-
Pin#32 of YMU759 and YMU759B is SDOUT (output pin of serial bus interface) and it is open drain pin.
-
Pin#5 of YMU759 and YMU759B is IFSEL, which is to select CPU bus interface. “High” level is for parallel interface
while “Low” level is for serial
