Bluetooth Audio Module

6.0 Layout Guidelines

BTM98-8AAm

6.0.1 Audio Layout

Route audio lines as differential pairs. The positive and negative signals

should run parallel and close to each other until they are converted to single-ended

signals. Use dedicated audio ground plane for entire audio section.

6.0.2 Antenna Design

Do not place GND plane or any metal directly under the antenna of

BTM-68D. To avoid any excess parasitic capacitance in the antenna feed line caused

by the RF test pin on the bottom side of the module, the area underneath the RF test

pin should also be left free from copper. Any metal in close proximity of the antenna

will have an effect on the antenna performance. Thus any metal should be placed as

far from the antenna as possible. The module should be placed to an edge of the PCB.
