Audio Concept

Audio HW architecture

The functional core of the audio hardware is built around three ASICs: RAPIDOYAWE engine ASIC, mixed signal

ASIC Avilma and D/A converter DAC33.

DAC33 converts digital audio signal to analog and is routed to the FM Transmitter and amplifier TPA6130

which provides an interface for the transducers and the accessory connector.

Integrated handsfree stereo speakers are driven by a D-class audio amplifier TPA2012D2.

There are two audio transducers:

• 7x11 mm dynamic earpiece

• Two 8X12 mm dynamic speakers

Avilma provides an output for the dynamic vibra component. All galvanic audio accessories are connected to

the AV accessory connector.

A Bluetooth audio and FM radio module, which is connected to the RAPIDOYAWE supports Bluetooth audio

and FM radio functionality.
