Hello

I have just putdown my screwdrivers :)


Yes it was three ICs


on the bottom-side , no heatsinks (digital reception, that's why i guess) , is
an AF9013-N1

on the top-side, with a heatsink : CX23885-13Z , PCIe A/V controler

on the top-side, with heat-sink + "radio-isolation" (aluminum box) XC3028ACQ ,
so the analog reception .

 
Its all on a PCIe bus, the reason why i baught it ... :)



To resume :


AF9013-N1

CX23885-13Z

XC3028ACQ


the drivers while scanning
