1. Generalities
1.1 Introduction
1.1.1 Overview
The main objectives for this board, discussed also with the marketing are:
Get lowest cost solution to enable BT for a maximum of IP terminals
Enable new usages like
o The phone is seen as a carkit for a smartphone
o The phone can exchange phonebook with a smartphone
From R&D point of view:
o The board must be small enough to be integrated easily into our ID.
o The board must integrate the antenna to avoid a re-certification for each phone
which would use it.
For this project, a pre-study has been done. See reference [1].
The choice is to do a daughter board with the chip CC2564 from Texas Instruments, with an
integrated antenna on the layout (Printed antenna).
1.1.2 Aim of the document
A pre-study has been done, in order to define the best choices for the whole solution, going from
antenna to the BT management software in the phone.
This document is intended to give all the technical inputs in order to make a BT daughter board
which will be used on the Alcatel-Lucent IP Phones.
A first step will be to use it on 8088, but we should care to make it possible to be used also on
nextgen phones.
1.2 Services provided by the feature or equipment
The BTDB will give a BT2.1+ EDR connectivity to the product where it is mounted into. The main
reasons of this daughter board are to have:
A common function usable on several phones without the need of RF expertise and full
BT qualification
A cost effective solution
1.3 External Interfaces

These correspond to the metal cut-holes. See chapter 7.4.3.
The VDD_IN pin can accept 2.2V to 4.8V. Typical value is 2.5V or 3.3V, but this depends on the
motherboard.
Check the CC2564 datasheet for more information.
The UART has by default the following characteristics (can be reprogrammed to up to 4Mbps)

This cabling supposes that the Host is in DTE mode. In case of DCE host, RTS and CTS are
straight, and not crossed.
