1. General description
The BGB203 combines the Bluetooth RF part, protocol stack, Link Controller (LC), Link
Manager (LM), and Host Controller Interface (HCI) firmware of the Bluetooth system
specification in one SiP with embedded software. Together with an antenna and a reference
clock this device forms a complete Bluetooth solution. In most cases this SiP will be attached
to a host, for example a GSM baseband controller or a PC processor.
The BGB203 is designed to be used for wireless links operating in the globally available ISM
band, between 2402 and 2480 MHz. The radio part is composed of a fully integrated,
state-of-the-art near-zero-IF transceiver chip, an antenna filter for out-of-band blocking, a
TX/RX switch, TX and RX baluns, and a basic amount of supply decoupling.
The device is a “Plug-and-Play” package that needs only 3 additional decoupling components
next to an antenna and reference clock for proper operation. Robust design allows for
ntrimmed components, giving a cost-optimized solution. Demodulation is done in
open-loop mode to reduce the effects of reference frequency breakthrough on reception
quality. An advanced offset compensation circuit compensates for VCO drift and RF
frequency errors during open-loop demodulation, under control by the baseband processor.
The circuit is integrated on a laminate substrate. It is connected to the main PCB through a
HVQFN48 compatible footprint. The RF port has a normalized 50 W impedance and can be
connected directly to an external antenna with a 50 W transmission line. A high-dynamic
range RSSI allows near-instantaneous assessment of radio link quality, and is used for output
power-control purposes.
The Baseband part and the RF interface of the SIP is designed to operate at 1.8V.
The RF part of the SiP is designed to operate from 2.75 V nominal supplies. Separate ground
connections are provided for reduced parasitic coupling between different stages of the
circuit. There is a basic amount of RF supply decoupling incorporated into the circuit.
The industry standard ARM7TDMI microcontroller with low power consumption is
integrated together with a flash memory and a SRAM. There are no provisions for external
controllers to directly access on-chip data memory. Communication with an external host,
for example a PC, GSM or PDA, is handled via the Host Controller Interface.

Industry standard interfaces such as PCM, UART, USB, and I C are supported by on-chip hardware.
