Preliminary

Functional Description

The ROK 101 007 is a complete
Bluetooth module that has been
specified and designed according to
the Bluetooth System v1.0B. Its
implementation is based on a high-
performance integrated radio trans-
ceiver (PBA 313 01 /2) working with a
baseband controller, a flash memory
and surrounding secondary compo-
nents features low energy consump-
tion for use in battery operated
devices.

Block Diagram

ROK 101 007 has five major opera-
tional blocks. Figure 11 illustrates the
interaction of the various blocks. The
functionality of each block is as
follows:
1.

Radio functionality is achieved by
using the Bluetooth Radio, PBA
313 01/ 2. Six operational
blocks are shown for the radio
section and their operation is as
follows:

1a) VCO-tank is a part of the phase

locked loop. The modulation is
performed directly on the VCO.
To ensure high performance the
VCO-tank is laser trimmed.

1b) Loop filter, filters the tuning

voltage of the VCO-tank.

1c) RX-balun handles transformation

from unbalanced to balanced
transmission.

1d) TX-balun handles biasing of the

output amplifier stage and
transformation from balanced to
unbalanced transmission.

1e) Antenna switch directs the

power either from the antenna
filter to the receive ports or from
the ASIC output ports to the
antenna filter.

1f) Antenna filter band-pass filters

the radio signal.

2.

The baseband controller is an
ARM7-Thumb based chip that
controls the operation of the
radio transceiver via one of the
interface methods; USB or
UART. Additionally, the base-
band controller has a PCM Voice
interface and I

2

C interface.

3.

A Flash memory is used together
with the baseband controller.
Please, refer also to the
Firmware

section.

4.

The power management block
regulates and filters the supply
voltage. V

CC

is typically 3.3V and

two regulated voltages are
produced, 2.8V and 2.2V

NOM

.

5.

An internal clock is mounted on
the module. The clock frequency
is 13MHz and is generated from
a crystal oscillator that guaran-
tees a timing accuracy within

±

20ppm.

Bluetooth Module stack

The Host Controller Interface (HCI)
handles the communication by the
transport layer through the UART or
USB interface with the host. The
Baseband and radio provides a
secure and reliable radio link for
higher layers.
The following sections describe the
Bluetooth module stack in more
detail. It is implemented in accord-
ance with and complies with the
Specification of the Bluetooth
System v1.0B.
