Hi,

Good Day.

Customer is using the ADCxxDJxx00 Evaluation Module and he is trying to figure out how to configure the output clocks. He is having a bit of trouble, though. Is there a tutorial that shows how to do this?

Please advise. Thank you very much.

Best Regards,

Hi Ray,

As far as I am aware, we do not have any instructions for setting output clocks with the LMK devices. Please allow me some time to create a document explaining this.

Hi Ray,

Here is the link to the users guide which will guide you through various clocking options available on the EVM.

Ray,

In addition to Neeraj's user guide more specific to the ADC12DJ5200RF, the customer may find this brief document helpful on LMK operating modes. This is written with respect to the LMK04828 however many ideas carry over to the LMK04832 device as well.

Hi Chase,

Good Day. Can you also tell me which pin or connection SYSREF comes out on? Thanks.

Are they using the LMK04828 or the LMK04832?

These devices have 7 output pairs with each pair comprised of a DCLKout and a SYSREF. For each DCLKout, there is a SYSREF output.

Ray, see the LMK04828 output dividers and sysref output pins on our ADC12DJ5200RFEVM schematics here on page 4. 6637199D_ADC12DJ5200RF EVM_RevD(-002)_Sch_.PDF.

Thanks, Chase
