FUNCTIONAL BLOCK DIAGRAM

Layout and PCB Design

Since the SY88713V 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 SY88713V’s 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.
