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.

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. Please see ordering guide for build option details. The surface-mount antenna socket used in the CX module is:

This can be used to clock an external D/A converter or DSP. SCLK, audio data bit clock at 64Fs. Allows for up to 32 audio data bits per sample word. SPDIF format output. Can support samples rates up to 192kHz, so the maximum instantaneous frequency on this pin is 24.576MHz. SPDIF input. Not used at present. Leave open. I2S or left justified audio data output. Not used at present. Leave open. Differential stereo output from PWM-DAC, right and left channels. These signals require analog low pass filtering. SMSC is not recommending using the PWM-DAC outputs because of the potential for high out-of-band noise and uncharacterized audio quality. SMSC recommends using an external D/A converter connected to AV2DATA0. I2S or left justified audio data input. Can be driven from an optional external A/D converter used to interface to iPod analog output or other analog audio sources. If not used, leave open. I2S or left justified audio data input. Not used at present. Leave open. This signal is configured as GPIO-17 and is currently not used. DM870A-internal pull-up. Leave this pin open. 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. 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. ETH_NRESET Low-active reset for the on-board ethernet PHY. This output is driven by the DM870A. GPIO-12. Leave this pin open. 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. 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. 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. SMSC CX Module 22 Revision 2.8 (09-30-12) SMSC CONFIDENTIAL JukeBlox Networked Media Modules CX Series Datasheet Ethernet signals between the PHY on the module and the external magnetics
(transformer). See Note 4. Maximum bit rate is 100Mbps. 3.3V push-pull outputs (max. 12mA) to drive the ethernet LEDs. 100Mbps speed mode and activity are indicated by the outputs being low. Connect to LEDs through 220ohm resistors. USB data signals, normally connected to type A connector, USB switch or iPod dock connector. Maximum bit rate is USB High Speed at 480Mbps. Analog input for monitoring USB type A connector power. Connect to the +5V power which is driving the USB type A connector power pins. If this pin drops below 4.6V, then the DM870A will drive the USBVBUSDRV signal low to control an external power MOSFET to disconnect +5V power from the USB type A connector. See Note 5. Logic output to control an external MOSFET that is in series with USB type A connector power. See USB_VBUS above and Note 5. JTAG port for DM870A. Leave open.

J3 pin numbers 61, 62 and 55 are not connected to any signal in the CX870-3K module. 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.

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.
