Output Termination
The SY88903 outputs must be terminated with a 50
load to V
CC
– 2V (or Thevenin equivalent).
Layout and PCB Design
Since the SY88903 is a high-frequency component,
performance can largely be determined by board layout
and design. A common problem with high-gain amplifiers is
feedback from the large swing outputs to the input via the
power supply.

APPLICATION INFORMATION
The SY88903 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.
