AM5708: Video DPLL SSC support

Part Number: AM5708

Hi, My customer is working om AM5708 design and has done some EMC measurements and some radiated emission levels of the display interface are to high.
He looked at the DPLL_VIDEO Registers and found in table 11-48 PLL_SSC_CONFIGURATION1 a reference to the SSC feature, with a note that the SSC feature is not supported.

His questions:
1) Is this going to be supported in the future?
2) Is the feature available but not tested/supported?
3) can customer use this function?

Thanks in advance,

Best regards, Patrick

ps: why is this non supported feature part of the documentation? (On e2e i found other references to this feature in TDA2 and DRA72X devices, but also not supported. quit confusing)

  • Hi Patrick,

    SSC feature is available, but not tested, thus not verified by TI. See the below e2e threads for more info:

    e2e.ti.com/.../565566
    e2e.ti.com/.../1964650
    e2e.ti.com/.../604515

    Regards,

    1) Is this going to be supported in the future?

    I can not confirm. You should check in any new version of the AM57x documents regarding the status of SSC.

    2) Is the feature available but not tested/supported?

    Yes

    3) can customer use this function?

    The customer can use it, but at his own risk. The customer should fully test and validate that feature on his custom board. TI do not recommend that feature usage, if possible you should avoid it.

    Regards,
    Pavel
