Oticon Radio Model - Quick Installation Guide

Radio Model Name: Audio Streaming Module

The Audio Streaming Module is an accessory board completely equipped with both a microcontroller host and two radio systems on board the same Printed-

Circuit-Board (PCB). Besides the host and the radio systems the module also includes a Digital-Signaling-Processor (DSP), an audio codec, a power management

circuit, flash memory, a tele coil and small discrete components.

The two radio systems are

- a low power, inductive radio transmitter working at 3.84 MHz

(including no active receiver) and

- a 2.4GHz radio transceiver, which is intended both for

proprietary use and compatible with Bluetooth enabled wireless

accessories, such as wireless headsets and mobile phones.

The low power, inductive radio transmitter is consisting of a Complex

Programmable Logic Device (CPLD) fed with data from the host, an RC

clock oscillator and two H-bridges feeding the modulated RF signal at

3.84MHz to a dedicated ferrite coil antenna (its connector can be seen in

the bottom side drawing to the right). The CPLD can also transmit the

RF signal via an external and dedicated neck loop antenna in stead of

the internal coil antenna. (The neck loop is attached through two holes

in the plastic frame to dedicated springs on the PCB, which can be seen

in the top side drawing to the right).

The 2.4 GHz transceiver is consisting of a completely integrated radio

transmitter and receiver inside a Bluetooth chip from Cambridge Silicon

Radio (CSR). The BT chip feeds its RF signal to a dedicated PCB

antenna onboard (see drawings next page). The Bluetooth chip is

controlled by the μcontroller host, and audio data between the two chips

is handled by the DSP.

The module mounted with its dedicated ferrite coil antenna in a plastic

frame is depicted to the right:
