DS280DF810: request schematic review

Hi,

Below attached schematic is from one of our most important customer, so could you check whether there's any potential problem or not?

    Hi, I reviewed the schematic. My inputs below.

    Checked and ok

    • VDD decoupling
    • Oscillator for CAL_CLK_IN
    • High-speed inputs and outputs -> no external AC coupling caps as the retimer implements integrated AC coupling caps
    • ADDR pin strap options
    • READ_EN_N floating for SMBus Slave Mode
    • ALL_DONE_N floating
    • INT_N to system input
    • TEST pins floating

    Comments

    • EN_SMB is 2.5V LVCMOS input pin. Recommend to use 1kOhm pull-up to 2.5V for normal operation in SMBus Slave Mode
    • Assuming that retimer SDA and SCL are pulled to 3.3V somewhere on the system boards

    Cordially,
