OMAP 4460 - Connect CSI2 Tx through LVDS to OMAP 4460 CSI2 Rx

Other Parts Discussed in Thread: 4460

Hello,

Is there a way to connect CSI2 Tx with OMAP 4460 only through LVDS?

I know this is a long shot, but if there is a way to do this it would be good to know. Basically, is it possible to avoid having transmission over DpDn lines that will have to comply with MIPI D-PHY protocol, especially Low Power states?

Thank you very much in advance

  • Hello Ranko,

    Sorry for late delay.

    Below are the answers of your questions:

    1. Is there a way to connect CSI2 Tx with OMAP 4460 only through LVDS? -To connect CSI2 Tx with OMAP4460 is needed to use a MIPI CSI-2 TX bridge. The MIPI CSI-2 TX Bridge converts a standard parallel video interface into CSI-2 byte packets. For example see SN65LVDS315 camera serializer and TC358746 camera bridge.

    2. Is it possible to avoid having transmission over DpDn lines that will have to comply with MIPI D-PHY protocol, especially Low Power states? - The MIPI D-PHY function can support up to four data lane modules and one
    clock lane module. Reverse direction escape mode is not supported. The lane module polarity and
    positions are configurable; that is, any lane module can be chosen as the clock lane module, and the
    DX/DY data pad for each lane module can be configured as DP or DN pins defined. The configuration and
    the selection of D-PHY mode, data/clock, or data/strobes are done through the control module (see
    Chapter 18, Control Module). The only exception is the four-data-lane use case, in which one corner lane
    is allowed to be only a data lane.

    Best regards,

    Yanko
