Electrical Characteristics
Table 7
4.1.4
Each i.MX 6Dual/6Quad processor has two external input system clocks: a low frequency (RTC_XTALI)
and a high frequency (XTALI).
The RTC_XTALI is used for low-frequency functions. It supplies the clock for wake-up circuit,
power-down real time clock operation, and slow system and watchdog counters. The clock input can be
connected to either an external oscillator or a crystal using the internal oscillator amplifier. Additionally,
there is an internal ring oscillator, that can be used instead of RTC_XTALI when accuracy is not important.
The system clock input XTALI is used to generate the main system clock. It supplies the PLLs and other
peripherals. The system clock input can be connected to either an external oscillator or a crystal using the
internal oscillator amplifier.

On-chip LDOs are designed to supply the i.MX 6Dual/6Quad loads and must not be used to supply external loads.
VDD_ARM_CAP/VDD_ARM23_CAP must not exceed VDD_SOC_CAP by more than +50 mV.
VDD_CACHE_CAP must not exceed VDD_ARM_CAP by more than 200 mV. VDD_ARM_CAP must not exceed
VDD_CACHE_CAP by more than +50 mV.
