Part Number: CDCE6214


After we configure 100mhz and 125mhz, all channels only output 100mhz. Please help to check whether there is any problem with the configuration。

    Hello,

    Increasing PFD frequency by setting the input doubler to 1 will provide better performance.

    However, this does not impact the output frequency correctness. It's most likely I2C communication problem. First make sure that the USB communication is green. Then click "scan I2C bus". Then write all registers.

    Finally, click "recalibrate" (which recalibrates the PLL) then check lock status.

    Regards,
    Hao
