* Connector on board, but requires board modification to enable the connector.

+ The position of the X in the One Ant. column indicates that there is one external antenna connector provided. The position of the X in the Two Ant. column indicates that there are two external antenna connectors provided. Do not use a module which has two external antenna connectors with only one external antenna connected. Leaving one antenna socket open will degrade WiFi performance. SMSC recommends always using modules with two external antennas for best performance.

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 +1.9V regulator circuit. SMSC recommends that customers follow the +1.9V supply voltage requirements given in this data sheet, and follow the +1.9V 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. 6.0.1 Antenna Considerations Here are the antennas used for certification:

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:

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. 32 COMPANY CONFIDENTIAL 9.1.1 Power up, Reset and Power Down Timing 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.
