DDC264 communication interface

Other Parts Discussed in Thread: DDC264EVM, DDC264

Hi I have successfully evaluated the DDC264 chip using the DDC264EVM evaluation module. 

Now I am looking at incorporating the DDC264CK chip into my project on a custom PCb. I am planning to use an mBed LPC 1768 microcontoller platform to implement the control structure for my board. I do not have familiarity with FPGA and HDL.

Is there a C or C++ library or interface program (for MSP430 or others microcontrollers) for interfacing with the DDC264CK chip to configure it and also retrieve data back from it?

From the data sheet it appears that the digital interface interface is not very straightforward. Any information or help in this regard will be much appreciated. 

Regards,

    Dhe,

    Glad to hear your evaluation is going well. 

    Unfortunately we do not offer a C/C++ interface program, customers usually write their own code since they are incorporating the devices into a much larger system which they want to fully specify themselves. We do have a DLL that you can make calls to in order to communicate with the chip on a basic level although the rest of the digital timing will need to be programmed using the datasheet parameters. I can help answer questions you have about the timing specs on the datasheet. Please let me know if you would like the DLL.

    Thanks and Regards,

    Hi Adam,

    Thank you for the reply. Is this DLL for communicating with the chip using the evaluation board? Can you provide me a link to download this please.

    Also from Table 3 in the data sheet, the Max DCLK and CLK_CFG has been specified but not the minimum. What is the minimum clock speed for this communication interface? The microcontroller I am currently using cannot communicate at this clock speeds. I may need to change the microcontroller that I use in my end design based on this value.

    Regards,

    Hi Dhe,


    To your second question, as long as I know you can run those interfaces as slow as you want...

    Regards,

    Dhe,

    Please see the following thread for more information about communicating with the chip and the DLL. http://e2e.ti.com/support/applications/high_reliability/f/30/t/176526.aspx?pi82569=1

    This DLL is for the Evaluation board.
