Layout and PCB Design

Since the SY88913 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.

Figure 1. Differential Input Configuration

The SY88913 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.
