7.10.4 Clock Specifications

7.10.4.1 Input Clocks / Oscillators

Various external clock inputs/outputs are needed to drive the device. Summary of these input clock signals is as

follows:

• MCU_OSC0_XO/MCU_OSC0_XI — external main crystal interface pins connected to the internal high-

frequency oscillator (MCU_HFOSC0), which is the default clock source for internal reference clock

HFOSC0_CLKOUT.

• WKUP_LFOSC0_XO/WKUP_LFOSC0_XI — external crystal interface pins connected to internal low-

frequency oscillator (WKUP_LFOSC0), which sources optional 32768 Hz reference clock.

• General purpose clock inputs

– MCU_EXT_REFCLK0 — optional external system clock.

– EXT_REFCLK1 — optional external system clock.

• External CPTS reference clock input

– CP_GEMAC_CPTS0_RFT_CLK — optional reference clock input for CPTS_RFT_CLK.

• External audio reference clock inputs/outputs

– AUDIO_EXT_REFCLK[1:0] — optional McASP high-frequency input clocks when configured to operate as

an input.

For more information about Input clock interfaces, see Clocking section in Device Configuration chapter in the

device TRM.
