FUNCTIONAL DESCRIPTION

5.1 Baseband

5.1.1 Overview

The baseband is based on Ericsson Technology Licensing Baseband Core (EBC) and it is fully compliant

– Point to multipoint (up to 7 Slaves)

– Asynchronous Connection Less (ACL) link support giving data rates up to 721 kbps.

– Synchronous Connection Oriented (SCO) link with support for 1 voice channel over the air interface.

– HW support for all packet types:

– ACL: DM1, 3, 5 and DH1, 3, 5

– SCO: HV1, 2, 3, and DV1.

– Support for three PCM channels in the PCM interface .

– Architecture gives ultra-low power consumption.

– Ciphering support up to 128 bits key, configurable by software.

– Receiver Signal Strenght Indication (RSSI) support for power-controlled links

– Flexible voice formats to Host and over air (CVSD, PCM 16/8-bit, A-law, µ-law)

– High quality filtering of voice packets enabling excellent audio quality.

– Scatternet support, communication between two simultaneously running piconets.

– Low level link controller.

– Specific external power amplifier (PA) control for class1 support

– Extended wake-up and interrupt functionality for HID support
