Is there a level conversion chip with SPI communication clock above 32MHz?

Hi Fang,

This seems to be the same question you have asked several times. Could you help clarify the gap? Thanks.

Best Regards,

Michael.

Because I can only see the unit BPS of data rate in the specifications of these level conversion chips, and I don't see the explanation HZ of frequency. My goal is to find a bidirectional level conversion chip that can meet the requirements of SPI communication frequency greater than 32MHZ from 5V to 3.3V, and needs to ensure that data transmission can be undistorted at around 32MHZ.

Hi Fang,

Please see Is there a level conversion chip that supports I2C and SPI, and the communication clock for SPI level conversion is not distorted above 25MHz? for recommendations.

For example, the below is from the TXU0304 datasheet (5V to 3.3V up to 125Mbps i.e 62.5MHz), thanks.

Best Regards,

Michael.
