BGB203

www.DataSheet4U.com BGB203 Bluetooth System-in-a-Package radio with baseband controller Rev. 1.0 — 2005 July 28 Product Shortform Datasheet 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 untrimmed 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...
