deployment. The GPS system
provides precision 1 pps timing
that allows the AP to meet the
demanding  0.05 ppm required
by the AP for communication.
Digital Clocks
26 MHz for digital, RF, AFE
33.33 MHz for CPU PLL
25 MHz for Ethernet
11.0592 MHz for UART

*** As of September 2012 the countries currently approving ETSI RFID power levels for the AP include
France, Germany, Ireland, Liechtenstein, Spain, Switzerland, and United Kingdom.
2.2 RF Subsystem Block Diagram
The AP RF subsystem operates as a half-duplex transceiver. The SPDT switches allow
connection from the antenna to one of three paths:
 TX high power
 TX low power
 RX
The Cavity Filter is only used in the FCC/IC configuration, specifically to avoid the 2483 MHz
Restricted Band when near max power. It also provides excellent out-of-band rejection.
