Hi Hasan,

ehm, I would like to disagree a bit. The THS7347 is a mixed analog digital chip and has analog and digital ground pins (DGND and AGND). Drawing a proper layout might not be trivial at all. A good datasheet should contain information of how to handle the two grounds. And it should show an example layout. But the datasheet of THS7347 doesn't contain anything. Not good...
