Hi guys,
i am working with real-time implementation of a codec on BF533 eval board. part
of my plan to have faster encoder processes before a frame buffering completes,
is to make my clock faster.
currently, i am using CCLK'0MHz and SCLKTMHz. I am planning to double the
cclk rate. are there any drawbacks in doing this? are there any possibility of
hardware destruction (like transistor burning)? i just want to make sure that
aside from timing, there will be no other problems in using higher clock
rate.
thank you very much for your support.
God bless,
regards,
mac
higher clock drawback?

Check the manual for that specific part. If the max core clock is 600MHz
you should be fine, but if it is 500MHz then it probably won't work. I
don't think it will hurt the hardware, I think the timing on the latches
won't have enough setup and hold margin and things just won't behave
properly.
