Hi All,

What are the pull-up or pull-down resistors for BCLK, FSYNC, and DIN?

Hi Ishiwata-san,

BCLK, FSYNC, and DIN should not have any pull-up or pull-down resistors. At most, series termination resistors can be used for long clock traces vulnerable to reflections.

Hi Jeff-san,

Thank you for your answer.

Do BCLK, FSYNC and DIN have built-in pull-down resistors like MDx?

Best Regards,
Ishiwata
