Audio concept

Audio HW architecture

The functional core of the audio hardware is built around two ASICs: RAP CMT engine ASIC and mixed-signal

ASIC (N2200).

The mixed-signal ASIC (N2200) provides an interface for the transducers and the accessory connector. Because

audio amplifiers are also integrated into the ASIC, the only discrete electronics components needed for audio

paths are audio filtering components and EMC/ESD components.

There are three audio transducers:

• 8 mm dynamic earpiece

• 16 mm dynamic speaker

• two digital MEMS (Microelectromechanical Systems) microphones

In addition to the audio transducers, N2200 also provides an output for the dynamic vibra component.

All galvanic audio accessories are connected to the system connector.

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

FM radio functionality.

There is also a separate application ASIC for Symbian applications.
