ADS4449: ADS4449: SPI logic level

Part Number: ADS4449

H i team,

The ADS4449 datasheet describes "All digital inputs support 1.8-V logic levels. SPI supports 3.3-V logic levels". It means that SPI supports 1.8V logic level and 3.3V logic level. But the typical value of High-level Output voltage of SDOUT is DRVDD (1.8V). When ADS4449 communicates with 3.3V chip in SPI, does SDOUT signal line need additional circuit to convert to 3.3V? In other words, can the 3.3V chip recognize the SDOUT high-level of ADS4449?

Best Regards,
Amy
