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 p ublic 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 integrate d RF

Module. Additional measurements (15B) and/ or equipment authorizations

(e.g Verification) may need to be addressed dependin g 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 resp onsible 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
