2.3 Auxiliary Port
The BM63 module supports analog (line-in) signals
from the external audio source. The analog (line-in) sig-
nal can be processed by the DSP to generate different
sound effects (multi-band, dynamic range compression
and audio widening), which can be set by using the
DSP tool.

CAPLESS MODE
2.4 Analog Speaker Output
The BM63 module supports the following analog
speaker output modes:
• Capless mode – Recommended for headphone
applications in which capless output connection
helps to save the BOM cost by avoiding a large
DC blocking capacitor. Figure 2-7 illustrates the
capless mode.
• Single-ended mode – Used for driving an external
audio amplifier where a DC blocking capacitor is
required. Figure 2-8 illustrates the single-ended
mode.
