1. Can S32K14x's PLL accuracy be ≤ ± 0.3% over the entire life cycle and temperature range. No relevant information is mentioned in the Datasheet.
2. The S32K14x external crystal input mentioned here is a maximum of 50MHz. Is it an oscillator input? From other places in the Datasheet, you can see that the external crystal's range is 4-40 MHz, which means that crystal only supports direct input up to 40MHz?
