Electrical characteristics

Each i.MX RT1160 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 watch-dog counters. The clock input can be

connected to either external oscillator or a crystal using internal oscillator amplifier. Additionally, there is

an internal ring oscillator, which can be used instead of the RTC_XTALI if 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 external oscillator or a crystal using internal

oscillator amplifier.

2 This specification is for an externally supplied clock driven to EXTAL32 and does not apply to any other clock input. The

oscillator remains enabled and XTAL32 must be left unconnected.

3 The parameter specified is a peak-to-peak value and VIH and VIL specifications do not apply. The voltage of the applied clock

must be within the range of VSS to VDD_SNVS_ANA.
