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 requires only a battery to be mounted together with its ferrite coil antenna in an external plastic shell (as shown on the previous page). The two microphones of the module are mounted onboard its PCB and the module requires no speaker as all sound is streamed wirelessly to any connected devices (e.g. Oticons wireless hearing aids and/or mobile phones). The module has its power management subsystem including all voltage regulators and the charging circuit on board. Also all data interfaces (input-output) on the board are buffered.
