Hi TI expert,

Could you share us the TDA4VEN clock tree?

Can we only use a 25MHz Crystal for WKUP / MCU domain and MAIN domain?

Best Regards

The TRM shows boot mode selects of 24, 25, and 26MHz.

Hi Kevin,

If the BOOTMODE selects 25Mhz, do we only need to use 25Mhz Crystal on MCU_OSC0, and do not need to use a 32.768Khz crystal oscillator on WKUP_LFOSC0?

The LFOSC will be used in a limited number of places. The primary clock frequency will be supplied the 25MHz crystal (and PLLs).
