ZigBee- Ready RF Transceiver Module CTL3576/7/8/9

1. General Description

The CTL357x RF Transceiver Module is compact surface mounted Module specially designed for Ember ZigBee™ protocol stack for wireless networks, EmberZNet, based on IEEE 802.15.4 standard in the 2.4GHz world-wide ISM band. The complete module is only 32.4 x 25.4 x 4.1 mm. It integrated a 2.4GHz, IEEE 802.15.4-2003 compliant transceiver with a 32-bit network processor (ARM Cortex-M3 Processor) to run EmberZNet. They contain embedded Flash and integrated RAM for program and data storage. It utilizes the non-intrusive SIF module for powerful software debugging and programming of the network processor.

Note: the output power of EM357 should be configured lower than -15dBm for 2480M channel to Comply FCC requirement.

The use of RF frequencies and maximum allowed RF power should according to different national regulations. The CTL3576 is complying with the applicable regulations for the world wide 2.4GHz ISM band.

12. PCB Layo ut Recommendations

Please reference Mechanical Dimensions shown in next section for PCB layout.

The area underneath the module should be covered with solder mask in order to prevent short circuit on the test pads on the back side of the module. A solid ground plane under the module is preferred.

As the module integrated with onboard PCB trace antenna, the mounting position of the module will have great impact on the RF performance. There should not be any trace, ground plane or metal part underneath or nearby the area of the onboard PCB trace antenna. The figure below shows an example how the module positioned on the mother PCB.

FCC STATEMENT:

1. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:

(1) This device may not cause harmful inter ference, and (2) this device must accept any interference received, including interference that may c aus e

undesired operation.

2. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.

NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or m ore of the following measures:

-- Reorient or relocate the receiving antenna.

-- Increase the separation between the equipment and receiver.

-- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

-- Consult the dealer or an experienced radio/TV technician for help.

FCC Radiation Exposure Statement

The modular can be installed or integrated in mobile or fix devices only. This modular cannot be installed in any portable device, for example, USB dongle like transmitters is forbidden.

This modular complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. This modular must be installed and operated with a minimum distance of 20 cm between the radiator and user body.

If the FCC identification number is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording suc h as the following: “Contains Transmitter Module FCC ID: DI2-CTL3579

when the module is installed inside another device, the user manual of this device must contain below warning statements;

1. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:

(1) T

his device may not cause harmful interference.

(2) This device must accept any interference received, including interfere nce that may cause undesired operation.

2. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.

The devices must be installed and used in strict accordance with the manufacturer's instructions as described in the user documentation that comes with the product.
