LMX2594EVM: LMX2594EVM artwork?

Part Number: LMX2594EVM
Other Parts Discussed in Thread: LMX2594

Where can I find layout/artwork for LMX2594EVM? Datasheet makes a distinction between VCO ground and digital ground (i.e. decouple VCCDIG to digital ground, decouple VbiasVCO to VCO ground) . I want to see how these ground are connected to each other on the eval board. Are they each connected to directly to common plane (which would make the datasheet guidance meaningless)?

    David,

    Short all the grounds to the center ground plane and to the DAP of the device.   So yes, connect to a common ground plane and the description in the datasheet for the grounds could be considered "meaningless" or at least for academic interest only.

    We did some experiments trying to separate the grounds and found that it did not improve spur performance.

    Also, attached are the gerber files for the LMX2594.
