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. The surface-mount receptacle parts:

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 voltagethan 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. dat_CX860_CX870_1_7_datasheet_c.doc PRELIMINARY - CONFIDENTIAL Version 1.7 May 13th 2011 - Page 19 of 23 Preliminary Data Sheet: CX Series JukeBlox Networked Media Modules 9.1.1 Power up, Reset and Power Down Timing Voltage Power Up Power Down

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. dat_CX860_CX870_1_7_datasheet_c.doc PRELIMINARY - CONFIDENTIAL Version 1.7 May 13th 2011 - Page 20 of 23 Preliminary Data Sheet: CX Series JukeBlox Networked Media Modules 10.
