SMSC does not certify all module variants for all countries. Please see above table for those module versions for
which certain certifications have already been done.
Please contact your SMSC sales office for the latest information about which modules are certified for which
countries, and arranging for additional certification for your chosen module if needed. Any additional certifications will
need to be paid for by the customer.
Product manufacturers are responsible for the end product certification.
SMSC can help manufacturers to prepare for the WiFi Alliance tests by providing an example test plan and the
required commands to enable special test modes. Please contact your SMSC sales office about WiFi Alliance logo
certification assistance.
The CX module has received Limited Module Approval (LMA) from FCC. This is because the CX module does not
have a built-in +3.3V regulator circuit. SMSC recommends that customers follow the +3.3V supply voltage
requirements given in this data sheet, and follow the +3.3V power supply design given in “CX Module Power
Supply_V1.1.pdf” document or later version. If the power supply recommendations are followed, then customers will
not need to go through formal certification of the product for WiFi related RF behavior for FCC. It is the product
manufacturers responsibility to make sure that the power supply recommendations are followed, and that the RF
behavior meets the certification requirements when the module is installed in the final product.
Please check the SMSC/BridgeCo Customer Portal at https://portal.bridgeco.net/ for documents about WiFi
certification and recommended interfacing and power supply schematics.

Notes about antenna changes:
1) Equivalent antennas from other manufacturers may be substituted, and then marketed
without a Class II permissive change
2) Equivalent antennas must be of the same type (e.g. dipole, PIFA, etc.), must be of
equal or less gain than the antennas listed and previously authorized under the same FCC
ID, and must have similar in band and out of band characteristics (consult specification
sheet for cutoff frequencies).
3) In case of new antenna types, or higher gain antennas, a Class II permissive change is
required and compliance with FCC section 15.203 must be met.

8 Connectors and Connections
8.1 WLAN UFL Antenna Connector (optional)
The module includes two PCB strip antennas operated in diversity mode. Alternatively, one or two coaxial antenna
connectors are provided for connecting external (to the module) antennas. The choice between using the strip
antenna or using the coaxial sockets is a build option, determined by the position of surface mount capacitors on the
module PCB. If the PCB antennas are chosen, then diversity mode is always used. If external (to the module)
antenna sockets are used, then two external antennas should be used to provide 2X diversity operation.
If external antenna is used, please choose the proper part number indicating two external antenna sockets. Do not
use a module which has two external antenna sockets with only one external antenna connected; this will result in
reduced WiFi performance.

PDOUT0 I Factory Reset. GPIO-04. Return the CnE to factory settings. High-active input, DM870A-
internal pull-down. Pull to GND with a 10kohm resistor, unless return to factory settings
from a hardware control is needed. Normally, return to factory settings is controlled from
the host controller via SPI register. This pin is only monitored during the boot up process.
VCO0 I Infrared sensor input. GPIO-05. This is a Schmitt-Trigger input and can handle inputs with
slow slopes. Used for aDMP firmware builds for infrared remote control sensor output
connection to DM870A. For applications with a host controller, pull this pin to +3.3V via a
10kohm resistor.
AV3CLK O ETH_NRESET Low-active reset for the on-board ethernet PHY. This output is driven by
the DM870A. GPIO-12. Leave this pin open.
AV3CTRL0,
AV3CTRL1 I/O I2C_SCL, I2C_SDA bus created by GPIO-13 and GPIO-14.
No internal pull-ups; Use 4.7kohm pull up resistor on each pin to +3.3V. Maximum
frequency is 400kHz.
NRESET_MOD I Low-active input to reset the module. This signal must be driven by an external reset
generator, or by a GPIO output from a host controller. See the application section of this
data sheet for the timing requirements for NRESET_MOD. Includes internal 10K pull-up
resistor to +3.3V.
NPD_RF I Active low input to shut down the power for the 802.11 RF section. Internal 10kohm pull-
up resistor to +3.3V. Leave open if powering down the RF section is not required.

9 Application Guidelines
9.1 Power Supply sequencing and Reset Timing
There are strict power sequencing and reset timing requirements.
• Power up the I/O voltage (3.3V) first and hold NRESET_MOD low.
• The core voltage (1.2V) must never be higher than (I/O voltage +0.5 V).
• The core voltage (1.2V) must be within the specified core voltage limits less than 300ms after the I/O voltage
(3.3V) reaches the specified I/O voltage limits.
• Throughout the power down process, the 3.3V supply must maintain a higher voltage than the 1.2V supply,
until both have reached ground potential.
• To assure a proper IC reset, the power supplies must be present for a minimum time of 2ms before
NRESET_MOD is de-asserted.
Please see the power and reset timing figure in Section 9.1.1 below.
About 1.9V, the arrival of 1.9V supply should lag behind the arrival of the 3.3V. The delay between the 1.9V and the
3.3V is not critical. Typical delay is approximately 10ms, for example using 10kohm resistor and 0.1uF capacitor on
the enable pin of a 1.9V dc-to-dc converter.

9.2 RF Considerations
Note that overall system, RF and WiFi performance is significantly affected by the product design, environment and
the application. It is the responsibility of the product designer to ensure proper system level shielding (if required) and
to verify performance and fitness for the given product features and applications.
The WiFi performance will be affected by the RF environment surrounding the CX module. Please ensure that the CX
module is positioned in a “quiet” RF environment, as far away as possible from high frequency clock signals and any
other sources of RF energy. Also, make sure the antenna is not shielded by any metal objects, for example
loudspeakers or other metal parts. Please make sure that the power supplies, in particular the +1.9V supply, are quiet
and free from noise.
SMSC recommends that systems implementing AirPlay should use a module configuration that includes on-module
shielding, as well as paying particular attention to system configuration and shielding. In particular, SMSC is
recommending the use of the Bottom Shield versions of the modules, which allows greater freedom in antenna
positioning.
Also, please see the SMSC Application Note:
SMSCAppNote - CX870_Antenna_Placement_V1_4.pdf
regarding antenna positioning guidelines.
Please see below picture for the recommended keep out area and cable routing for the antennas.
