On-chip oscillators

The system oscillator (SYS OSC) is a crystal oscillator. The SYS OSC, in conjunction with an external

crystal or resonator, generates a reference clock for this chip. It also provides the option for an external

input clock to XTALI signal directly.

Each i.MX RT1170 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
