Try here: koala.ece.rice.edu/elec424/docs/ 6211dsk_production_sch.pdf Yes the AD535 has programmable rates, but this feature is ignored on the DSKC6x11 board because the board designers at DNA Enterprises did not bring out GPIO or other lines to allow the C6x11 software to access the clock multiplier chip that feeds the AD535.
