[1] Applying the maximum voltage results in maximum power consumption and heat generation. NXP recommends a voltage set point = (Vmin + the supply tolerance).

This result in an optimized power/speed ratio.

[2] VDD_ANAx_1P8 refers to VDD_ANA0_1P8, VDD_ANA1_1P8, and VDD_ANAVDET_1P8.

[3] Tj minimum temperature supported at startup where Tj = Ta.

4.1.6 Clock sources

4.1.6.1 External clock sources

The i.MX 93 processor is designed to function with quartz crystals to generate the frequencies necessary for operation. 24 MHz

for the main clock source and 32.768 kHz for the real time clock. External clock can be injected into RTC_XTALI if the frequency

precision and jitter precision are sufficient.

The XTAL input is used to synthesize all of the clocks in the system with the RTC_XTAL input contribution to time keeping and

low frequency operations.

Table 15 shows the interface frequency requirements.
