DESCRIPTION
The BGB110 TrueBlue Bluetooth radio module is a
short-range radio transceiver for wireless links operating in
the globally available ISM band, between 2402 and
2480 MHz. It is composed of a fully integrated,
state-of-the-art near-zero-IF transceiver chip, an antenna
filter for improved out-of-band blocking performance, a
TX/RX switch, TX and RX baluns, the VCO resonator and
a basic amount of supply decoupling. The device is a
“Plug-and Play” module that needs no external
components 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 AFC circuit compensates for VCO
drift and RF frequency errors during open-loop
demodulation.
The circuit is integrated on a ceramic substrate. It is
connected to the main PCB through a LGA (Land Grid
Array). A metal cap suppresses the effects of EMI (Electro
Magnetic Interference). The RF port has a normalized
50
impedance and can be connected directly to an
external antenna, with a 50
transmission line.
The control interface is compatible whith BlueRF
unidirectional JTAG RXMODE 2. The connection to Philips
Semiconductors VW2600X family of Bluetooth baseband
processors is straightforward.
Frequency selection is done internally by a conventional
synthesizer. The synthesizer accepts a reference
frequency of 13 MHz. This reference frequency should
either be stabilised by an external crystal or be supplied by
en external source. The 13 MHz clock signal is also made
available as a system clock to the baseband processor. It
can be switched off for power saving. In that case, a
3.2 kHz clock is provided for wake-up timing.
A 1 MHz reference, derived from the 13 MHz system
clock, is available externally to clock out the transmit data
from the baseband processor. The BGB110 also provides
a 2.048 MHz clock for PCM voice codecs
The circuit is designed to operate from 3.0 V nominal
supplies. Separate ground and supply 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 envelope is a leadless SOTtbdA package with a metal
cap.
CAUTION
This product is supplied in anti-static packing to prevent damage caused by electrostatic discharge during transport
and handling. For further information, refer to Philips specs.: SNW-EQ-608, SNW-FQ-302A and SNW-FQ-302B.
