Part Number: LMK03318

Hi E2E,

we had LMK03318 code which TI FAE provided to us before.
But he sick leave 2 week, we need to your support!


After we load the code and write it, no clock of each channel.
load code step as below,

Step 1 : choose .epr file
Step 2: write to SRAM
Step 3: Program EEPROM to SRAM

Did we have wrong step or have something wrong about code?

    Hi Julian,

    I'm not sure which page of EEPROM you are powering up with, so I'll take page 0 as an example. After reading back the EEPROM settings, I found that PLL is powered down and no output is available. So I don't expect any output using page0. Here's a screenshot of page 0 settings:

    Your sequence of EEPROM writing is correct. Just make sure that you scan the I2C bus before writing it. Use GPIO3 and 2 to set EEPROM page. For details, please refer to datasheet or user's guide. To select page0, set both GPIO3 and 2 to low before powering up the device. To read back EEPROM content, click "read all registers" in the toolbar after scanning I2C address.

    Let me know if you have more questions.

    Regards,
    Hao
