Other Parts Discussed in Thread: DM385

Hi all,

Does the DM8147 support the HiSPi through CSI2 interface (without HiSPi-parallel bridge)?

Regards,
Lajos

    Hi Lajos,

    I have checked the DM814x ISS TRM (available only under NDA), sections 2.3 ISS CSI2 PHY and 2.6 ISS CSI2, but I can not find any reference to HiSPi (high-speed serial pixel interface). Thus I assume DM814x does not support HiSPi through CSI2 interface.

    Also I found that AR0331/HiSPi is used with DM385, DM368 and DM8127 devices (not DM8147 device), with IPNC RDK. Please refer to the below links:

    Hi Pavel,

    As http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/716/t/214010.aspx mentioned, the AR0331 is connected to DM8127 via SN65LVDS324 (http://www.ti.com/ww/en/analog/interface/sn65lvds324.html), so it seems that the DM81xx platform does not support HiSpi interface directly.

    Regards,
