Are there any recommendation on what type of heat sink is required for the top of the AD9163 package? There's a brief mention in the data sheet, but no real details / requirements.
Something like this would be ok: V5618A Assmann WSW Components | Fans, Thermal Management | DigiKey
The majority of the heat will go through the package into the PCB. Proper thermal layout will be critical to keep the DAC cool. There should be a solid, thick layer of copper where the heat can be spread. The DAC should be well grounded and the thermal paths should not be cut off or the part will get hot.
