Output Termination
The SY88943V outputs must be terminated with a 50
load to V
CC
2V (or Thevenin equivalent).
Layout and PCB Design
Since the SY88943V is a high-frequency component,
performance can be largely determined by the board layout
and design. A common problem with high-gain amplifiers is
the feedback from the large swing outputs to the input via
the power supply.
DESIGN PROCEDURE
The SY88943V ground pin should be connected to the
circuit board ground. Use multiple PCB vias close to the
part to connect to ground. Avoid long, inductive runs which
can degrade performance.
