About a necessity of MCLK on AD1934 when SPI-ing

Hello ADI,

I have a question.

 

We are now trying to control DAC(AD1934) by SHARC(ADSP21489).

We are thinking to use DLRCLK for DAC PLL Input, not using MCLKI/XI, MCLOKO/XO pins,

 

Do we need to use MCLK when we configure registers by SPI?

 

Thank you

Best Regards,
