1. General
The CTL357x RF Transceiver Module is comp
Description
act 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 o
utput 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.
PCB Layout Recommendations
12.
Please refer
ence 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.

1. This
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.
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 more 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
