on page 8 of 28 Pin 47 and 48 are there DVDD, on page 9 of 28 the same pins are
DGND. What is correct pin layout (DVDD) or pin description (DGND)?
Pins 47 and 48 of the AD9952 are digital inputs (unused on AD9952) so they can
be connected either to VDD or to GND. The easiest solution is to connect them
both to ground.
