TDA2: EDA2x EVM CPU Board

Part Number: TDA2
Other Parts Discussed in Thread: X5777BXGABC,

Hi,

I was looking into the evaluation Board  TDA2x EVM CPU Board. (Literature Number: SPRUI51)

The Processor in the  EVM CPU Board is X5777BXGABC ( Jacinto 6) which is not TDA2x (TDA2SG or TDA2P)

Can I use the Schematics and Layout reference  on This  EVM as Reference Design for my Hardware PCB  Schematics design?

Are Both Pin To Pin, drive strength, thermal  Compatiable?

    Hi Lee,

    You are free to borrow good ideas from EVMs, however keep in mind that EVMs are designed to evaluate as much of SoC functions as possible. They are full of discrete logic and muxing which normally are not needed in a field design.

    X5777 is a pre-production, test device, therefore drive strength and thermal are not compatible with production devices. I think they are pin-to-pin compatible, but kindly check your TDA2's silicon revision pins in the respective datasheet. Or, use an EVM schematic with your silicon revision SoC.

    Regards,

    Stan

    Hi Stan,

    Just to verify , X5777 is a pre-production for TDA2?

    Presently, the system and software guys use the existing EVM CPU Board ( with X5777BXGABC) to test all the necessary features.
    The EVM is connected to 4 cameras.

    1. If my HW is build with TDA2AG (I re- use the sDDR3 and VIP inputs as EVM ) will the system speed performance affected ?

    2. The software can just port in to my TDA2AG Board without modification?

    Hi,

    Correct, X5777 timings, thermal, and performance are not all characterized and may not meet those of TDA2. This is an early silicon for software test.

    1. Speed performance - as per TDA2AG datasheet.

    2. I think yes. Provided that same TDA2 pins are used on the new board. Otherwise pinmux will need to be modified as required.

    Regards,
