1.3 Functional Description
The primary component on the module is the Broadcom BCM20730, which is a
Bluetooth 3.0 compliant basic rate single-chip. The baseband and radio have been
integrated into a single chip implemented in standard digital CMOS. The block diagram of
the module is shown in Figure 1.

Figure 1: Block Diagram
The BT3GMD-B47P employs an integrated ARM CortexTM-M3 microprocessor core
that runs software from the Link Control layer up to the Host Controller Interface (HCI).The
baseband portion of the BT3GMD-B47P performs all the time-critical functions required
for high-performance Bluetooth operations.
The radio incorporates the complete receive and transmit paths, including PLL, VCO,
LNA, PA, upconverter,downconverter, modulator, demodulator, and channel select
filtering.
The BT3GMD-B47P on-chip keyboard scanner is designed to autonomously sample
keys and store them into buffer registers without requiring host microcontroller
intervention. A state machine of three states(Idle, Scan, and Scan-End)controls the
keyscan block.
The module has a SPI interface. The interface has a 16-byte transmit buffer and a
16-byte receive buffer .To support more flexibility for user applications. The module acts
as an SPI master device that supports 1.8V or 3.3V SPI slaves.

2.1 Reference Schematic
The most recent schematic , bill of material ,and layout file are available
from the ITON Technology Limit. Contact your ITON representative for details.
2.2 Layout Considerations
The BT3GMD-B47P module is placed at the location where the antenna is
away from the power supply(i.e.,BT1 Battery contacts)and any digital signal
traces. There should be no key matrix membrane under the antenna area and
the user’s hand should not be over the antenna area when the keyboard is in use.
The antenna keep-out area which is 5mm around the parameter of the module
region is shown in the red dotted box. PCB material and signal traces should not
be placed within the antenna keep-out area to assure optimum antenna
performance.

Attention: Limited Modular Approval ‐this RF Module may not be sold to the generic public and
requires professional installation. Due to the fact that this RF Module is not equipped with an own
shielding, the end‐product incl. this RF Module has to show compliance to the FCC rules
(15B/radiated emissions).
(OEM)Integrator has to assure compliance of the entire end‐product incl. the integrated RF
Module. Additional measurements (15B) and/ or equipment
authorizations
(e.g Verification) may need to be addressed depending on co‐location or simultaneous
transmission issues if applicable.
Integrator is reminded to assure that these installation instructions will not be made available to the
end‐user of the final host device.
With the low output power, this RF Module meets the FCC SAR exemption.
The final host device, into which this RF Module is integrated "has to be labeled with an auxiliary
lable stating the FCC ID of the RF Module, such as" Contains FCC ID: QTG-ZKMS
The RF Module is powered by DC ,the antenna is PCB antenna and the antenna gain is 2 dBi.
This device complies with part15 of the FCC rules. Operation is subject to the following two
conditions:
(1) this device may not cause harmful interference, and
(2)this device must accept any interference received, including interference that may cause
undesired operation. "should be placed also on the device or alternatively within a prominent
location of the users manual
Changes or modifications to this unit not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment.
This module is intended for OEM integrator. The OEM integrator is still responsible for the FCC
compliance requirement of the end product, which integrates this module. Due to missing shielding
the module is strictly limited to integration by the Grantee himself or his dedicated OEM Integrator.
The integration is strictly limited into following host platform(s) that are electrically identical incl.
variations that are defined as Class I Permissive Change to the documented and certified samples
-Bluetooth Keyboard
under the control of the Grantee.
Additional hosts and/or platforms can be added via Class II Permissive Change by the Grantee.
This RF Module will be exclusively integrated into battery power host devices
under strict control of the Grantee.
