Generating SCLK on ADSP-BF537 Ez-Kit lite

Hi,

 

I am currently working on a project where I need to use the ADMP441 MEMS as an input to the BF537 Ez-Kit. I have connected the MEMS to SPORT1 through PG10-12 on the external connector. The MEMS can only run as slave through i2s, so I need to generate the control signals from the blackfin. The problem is, that I need a sample frequency of 48kHz, which means that RSCLK need to be 3.072MHz. Are there any way to generate this frequency on the Ez-kit, when the CLKIN is 25MHz?

 

Best regards,

Mads
