GPCE063A Application Circuit (MIC_IN and GPY0030A audio amplifier, for 2-battery use only)

Note*:

These capacitor values are for design guidance only. The recommended 32K XTAL features are ESR=11.2~35K and CL1=CL2 =20~30pF (including

PCB parasitic loading, for example, user should apply additional 14~24pF on X32I and X32O if PCB parasitic loading is 6pF)
