Hi Team,

I use 50MHz crystal input, and want to get 33MHz, 100MHz and 125MHz output.

Please kindly teach me how to configure LMK03318, through hardware or software.

Thanks

Hi Daniel,

Please use TICS Pro (www.ti.com/tool/ticspro-sw) to do configuration.

Here is a link to a small training series on using the LMK03328EVM and TICS Pro. I typically use CodeLoader rather than TICS Pro for programming.

Is it 33MHz or 33.333 MHz (33 + 1/3)?
For 33.333 MHz, all outputs can be derived from 5GHz VCO.
For 33 MHz, you may need another PLL; consider LMK03328.

Kind regards,
Lane
