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.

4.2.2 Reference Clock for WLAN
WIFI_XTALI and WIFI_XTALO are the pins used for the reference clock. The reference clock is the
primary clock source for the SWB-A51H. SWB-A51H supports 26MHz by default frequency.
and it can support 19.2/24/26/38.4/40/52MHz reference clock.
Reference clock source may come from either an external crystal or oscillator/TCXO source.
Three hardware solutions are used for the reference clock

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

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).
