DLPC3436: Application issues of chips

Part Number: DLPC3436
Other Parts Discussed in Thread: DLPDLCR160CPEVM, DLPDLCR230NPEVM

Tool/software:

The input of dlpc3436 has two types: MIPI DSI and Parallel (RGB888). The reference design is Parallel (RGB888). What are the differences between these two inputs, and what are the advantages and disadvantages of Parallel (RGB888) and MIPI DSI inputs? The most important thing is, if I want a reference solution for MIPI DSI, can you provide it? The specific product is a projection application for smartphones

    Alternatively, there may be other recommended reference solutions for smartphones that require small packaging and low power consumption

    Hello User,

    DSI is not supported on the DLPC3436 and have noted this.

    Your External Video Input interface options are FPD-Link and Parallel Port.

    Parallel Port requires more signals to be sent to the FPGA to work correctly. That would be the RGB888 data and the sync and clock signals as well. Usually an IC is needed to take HDMI input and convert to parallel port.

    FPD-Link will require less signals but requires diff. pairs for data transmission. The existing design support the original version of FPD-Link. You would still need to convert your data to FPD-Link interface and send to the FPGA in the DLPC3436 design.

    DSI requires less signals than Parallel Port. You could run less traces for a design. Depending on how familiar a user is with this interface it may be difficult to get working.

    I do not have power estimates between the interfaces.

    The smallest EVMs that TI still offers are DLPDLCR160CPEVM and DLPDLCR230NPEVM. The DLPDLCR160CPEVM can use DSI but you would likely need to make an adapter board to interface with it. The resolution is 640 x 360 and the controller will take DSI and parallel port. The DLPDLCR230NPEVM uses parallel port from a Raspberry Pi for video input. The resolution with XPR is 1080p @ 60 Hz. The controller and FPGA will accept Parallel Port and FPD-Link.

    These would be designs that should have schematics on TI.com. Usually one video interface is picked so if you want an example of the EVM using another will likely will not have one.

    Best,

    John
