ADC3662EVM: Programming CDCE6214

Hi Gus,

No, there is not a direct way to program the CDCE6214 on the ADC3662EVM with custom settings at this time. There is only access to preset sampling frequencies.

Are you able to share what frequencies you are looking to use, and what mode of operation for the ADC3662?

Best,

Dan

Hi Dan - thanks for the quick reply.

The eval board ADC3662EVM has an incorporated 10MHz crystal. I was thinking to use it as input for the CDCE6214 and then one output of the PLL use it as 10MHz for sampling frequency and another one to use it for digital clock for the digitalized data for serial communication (115200 baud rate for example). 

Checking the schematic, the mentioned connections are feasible, but in order to generate the mentioned clock trough the CDCE6214 I would have to modify its registers.

Any idea how to accomplish it, if possible?

Thanks,

Gus

Thanks a lot, Dan, appreciate the help!

What about populating the 0 Ohms resistors shown in the figure below and using the B bus from the FT4232?

Hi Amy,

I understand that using the CDCE6214EVM would be a method to set the CDCE6214 to meet my needs, but how could I integrate it to use it with ADC3662EVM? 

So far the CDCE6214 in ADC3662EVM is able to operate with a fix frequency, which is only for example (as described in the User Guide), but there is not desired if different frequencies of operation are required.

Thanks,

Gustavo

Hi Amy,

Check the CDCE6214EVM with more details, and although I was expecting to use only one board, that board will meet my needs.

Thanks, and sorry for my stubbornness,

Gustavo
