Samsung Electro-Mechanics Proprietary and Confidential 12/15 4.2 Reference and Sleep Clock 4.2.1 Optional External 32KHz Input Clock The 32KHz clock is used in low-power modes such as IEEE power-save and sleep. The SWB-A51H does not require an external 32KHz clock. By default, the SWB-A51H will utilize its internal 32KHz clock. If the end application has a more accurate 32KHz clock, then it can be supplied externally via the WIFI_CLK_32K pin. The WIFI_CLK_32K input clock timing and voltage requirements are shown below.

Samsung Electro-Mechanics Proprietary and Confidential 14/15 FCC Notice  Host device of the approved module shall be marked with the following item: Contains Transmitter Module FCC ID: E2XSWB-A52H or Contains FCC ID: E2XSWB-A52H 5.15- 5.25 GHz band is restricted to indoor operations only. Compliance with FCC requirement 15.407(c) Data transmission is always initiated by software, which is the passed down through the MAC, through the digital and analog baseband, and finally to the RF chip. Several special packets are initiated by the MAC. These are the only ways the digital baseband portion will turn on the RF transmitter, which it then turns off at the end of the packet. Therefore, the transmitter will be on only while one of the aforementioned packets is being transmitted. In other words, this device automatically discontinues transmission in case of either absence of information to transmit or operational failure. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. FCC CAUTION  Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. This transmitter must not be co-located or operated in conjunction with any other antenna or transmitter. When installing it in a mobile equipment This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment and meets the FCC radio frequency (RF) Exposure Guidelines in Supplement C to OET65. This equipment has very low levels of RF energy that it deemed to comply without
Samsung Electro-Mechanics Proprietary and Confidential 15/15 maximum permissive exposure evaluation (MPE). But it is desirable that it should be installed and operated keeping the radiator at least 20cm or more away from person’s body (excluding extremities: hands, wrists, feet and ankles).
