EVMK2H: Interfacing EVMK2H to ADS8588SEVM

Mohammed Abu Ahmed
Prodigy 90 points
Part Number: EVMK2H


Hello,

I would like to know if ADS8588SEVM can directly be interfaced with EVMK2H.

I have recently bought ADS8588SEVM which is an 8 channel, simultaneous sampling ADC for acquiring current, voltage waveforms for relay application in real-time. But I am facing difficulty choosing appropriate standalone DSP board for my ADC, on grounds of interfacing. Until I came across EVMK2H which appears to be a close fit for my application and requirements. My question is: Is it possible to remove the PHI controller that comes with ADS8588SEVM and connect MIPI 60 pin of the EVMK2H directly to the J9 pin of my ADS for interfacing and proper transfer of real-time data stream. Excluding all software issues that might arise.

Thank You.

    Hi, Mohammed,

    I think your question is more toward ADS8588 and if I understand correctly that you want to connect EVMK2H MIPI to ADS8588 J9 pin. Correct?

    Mohammed,

    Please provide more information about the implementation that you are considering.  What interface mode, what sample rate and how many active channels do you need?  What is the bandwidth of the data being collected?  Is the data collection sustained or captured in bursts?  What interface on the K2H device are you considering?

    Tom,

    INterface mode is Parallel interfacing

    The sample rate is 200KSPS 

    Active channels: minimum 6

    Bandwidth is around 16kHz 

    Data collection is continuous in real-time, hence sustained.

    Regarding the interface on K2H, I am not quiet sure, what interface is right to  be connected to, but I am considering to use the JTAG interface available on the emulator board.

    Mohammed,

    The JTAG interface is for debugging and emulation.  It is not a streaming data interface for data into the device.

    The K2H does have a parallel data interface but it is optimized for interface with memories like SRAM or NAND/NOR FLASH.  It was not optimized to support streaming data.

    The high-bandwidth, streaming data interfaces on the device are the SERDES interfaces like SGMII, PCIe or SRIO.  Therefore, if you want to interface to an ADC that requires high-bandwidth, streaming data into a processor, we recommend that you implement an FPGA to translate from the native interface on the ADC to a SERDES interface on the K2H.  The K2H then has sufficient DSP and ARM processing capability even for very intensive real-time processing.
