The chipset used supports this interface; therefore no external component is required. The host must support the PC16 interface as well. The card uses only the 16-bit interface. 2.2.
XXXXXXXX Rev X The 802.11 WLAN MAC protocol is implemented in firmware supporting BSS and IBSS operation. Low-level protocol functions such as request to send (RTS)/clear to send (CTS) generation and acknowledgement, fragmentation and defragmentation, and automatic beacon monitoring are handled without host intervention. 3.
XXXXXXXX Rev X The baseband and MAC chip contains an ARM946E processor core and the SRAM required for implementing the Media Access Control (MAC) functionality. The embedded firmware runs the 802.11 MAC layer control. The MAC control sends and receives packets and transfers data to and from the CF interface to the host computer of the handheld device. 3.4 Frequency Generation The MAC & Baseband chip has the voltage-controlled oscillator (VCO) required for the design.
