Clock Generation for TMS320C6672: Looking for alternative to EVM Design

Other Parts Discussed in Thread: CDCM6208, TMS320C6678, TMS320C6672, CDCE62005

Hello, I am doing a design using the TMS320C6672 and have been looking over the TMS320C6678 EVM Reference Schematics. I'm looking at how they generated the DSP clocks on page 23 and they are using a CDCE62005RGZT. This device requires that it be programmed first via SPI. I'm looking for an alternative part that does not require programming over SPI. My co-worker has found a part that does not require external programming and is configured using jumpers. The part he found was the  CDCM6208 from TI. I was wondering what others have tried to generate the DSP clocks.

 

Thanks,

joe

    Hi Joe,

    The CDCM6208 was been used extensively on our internal silicon verification platforms and on our KeyStone II EVM for the K2K product. It it s good alternative to the CDCE62005. You will have to look at the available clock configurations to see if any match your needs. While programming the clock is an extra step, the registers are stored in non-volatile memory eliminating the need to reprogram on every power cycle. 

    Regards, Bill

    Bill,

    Hi, thank you so much for responding to my post. I'm thankful that on the table for Clock Generators at TI's web site there is an option to filter on "Pin Configuration".  That makes finding an alternative part so much easier. The CDCM6208 seems like the best option.
