XC147 is 6.3V voltage
in REF design
Layout Notice :
- Decoupl ing CAP should be placed before RES
Layout Notice :
- Each Vcc pi n needs to be i ndi vidual ly decoupl ed.
- VCC0, VCC1, VCC2, and VCC3 should NOT be shorted
together at the device pins .
Layout Notice :
- Control Pi n C0, C1 should be shi elded by GND
with more Vias.
