Internal Oscillators

To reduce production board costs and application development time, all F2837xS devices contain two

independent internal oscillators, referred to as INTOSC1 and INTOSC2. By default, both oscillators are

enabled at power up. INTOSC2 is set as the source for the system reference clock (OSCCLK) and

INTOSC1 is set as the backup clock source. INTOSC1 can also be manually configured as the system

reference clock (OSCCLK). Table 5-18 provides the electrical characteristics of the internal oscillators to

determine if this module meets the clocking requirements of the application.

Table 5-18 provides the electrical characteristics of the two internal oscillators.

NOTE

This oscillator cannot be used as the PLL source if the PLLSYSCLK is configured to

frequencies above 194 MHz.
