FUNCTIONAL DESCRIPTION ratio of either the MPC823 CPUCLK, the BCLK output or a clock provided by the FPGA, virtually any clock frequency can be generated to within a fraction of a percent accuracy. The output range of the AV9110 device is from .5MHz to 76MHz but lower frequencies can be achieved with further division logic in the FPGA. The clock frequencies are programmed serially by the writing to the clock synthesizer address space via the CPU. A program is available from BSE to derive the various register values for programming the AV9110 given the desired output frequency and the reference input being used. 3 3-8
