==> for longer RTC time sustain after battery remove,
please refer to RTC design notice
Before you select BJT , please take power dissipation into consideration.
Refer to MT6323 design notice
Refer to MT6323 design
notice for Zener selection
Refer to MT6323 design notice
for Buck GND layout rule
Refer to GPS co-clock layout rule
refer to system analog LDO

Based on your system level design , if
better EOS performance is needed on your
system, please refer to EOS performance
