8. Connectors and Connections
8.1 WLAN UFL Antenna Connector (optional)
The module includes two PCB strip antennas operated in diversity mode. Alternatively, 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 either one
or two external antennae may be connected. Using two antennae is preferred since this provides 2X
diversity operation. Please see ordering guide for build option details.

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.
BridgeCo 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.
