Tool/software:
Hi, we are using TPS6521903 PMIC to power AM64 SOC in our product and testing its power-up sequence. The test result indicated that the ramp of MCU_OSC0_XI signal from SOC is approximately 6.7ms EARLIER than ramp of LDO2 output, different from the sequence example given in its datasheet, in which MCU_OSC0_XI should have been 1.5ms later.
We are wondering whether our sequence result is regular case and whether any potential problem exists in SOC or PMIC. Also we hope to distinguish potential reason making the ramp earlier. Thank you very much!
