Other Parts Discussed in Thread: CDCE62005,
Hello,
1. Can you recommend a good clocking chip to provide clocks to C6654? I looked at the evaluation board of C6657 and it uses CDCE62005. Is that good to use? I need to provide clock input to CORECLKP/N and DDRCLKP/N. If I don't need PCIe, is it okay to terminate and not provide clocks to PCIECLKP/N?
2. If I use CDCE62005, or equivalent, is it expected for the host to program the clock generator via SPI prior to deassertion of POR? If not can it clock out with some default settings? I'd like to operate the DSP at 850 MHz and I saw the C6657 eval board provides 50 MHz to DDRCLKP/N and 100 MHz to CORECLKP/N. Can I do the same? And if so, how can I default the clocks to these values?
Thanks,
Divakar
