Main Power Supply
These pins supply power to the main elements of
the circuit. They should be filtered to be as quiet
as possible.
Digital Output Power Supply
These supply pins are identified separately from the

Clock Generator Power Supply
The most sensitive portion of the AD9887A is the
clock generation circuitry. These pins provide
power to the clock PLL and help the user design for
optimal performance. The designer should provide
noise-free power to these pins.
Ground
This is the ground return for all circuitry on the
chip. It is recommended that the application circuit
board have a single, solid ground plane.
