Other Parts Discussed in Thread: CDCM6208

Hi,

Customer will program CDCM6208 in I2C. Regarding Figure35 of the datasheet, when should registers be written for initial setting?

Best Regards,

Kato

    For either I2C or SPI host mode, register access can begin once PDN is pulled high either: through internal pull-up (to DVDD rail), or PDN pin is externally driven high (e.g. by PGOOD output of the power supply regulator or host controller, once VDD power rails are within regulation).
