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.

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.
