Figure 46: OSD3358-SM-RED clock circuit
Figure 46 shows the circuit for OSC0 and OSC1 clock inputs of OSD335x-SM in the OSD3358-
SM-RED Board. More information on the inputs and circuit design can be found in AM335x TRM

NOTE:
The version of the PMIC used within the OSD335x-SM is not capable of supporting
RTC-only low power mode. However, the internal RTC LDO is still used to power the RTC
module by pulling RTC_KALDO_ENN (M16) to GND through a 10K resistor.
