2.2 Main Chipset Information Item Vender Model # Single-Chip2x2 MIMO MAC/BB/Radio Atheros AR9280 (Merlin) 2.2.1 MAC/Baseband/Radio Processor The Atheros AR9280 is a highly integrated single-chip solution for 2.4 and 5 GHz 802.11nready wireless local area networks (WLANs) that enables high-performance 2x2 MIMO configurations for wireless station applications demanding robust link quality and maximum throughput and range. The AR9280 integrates a multi-protocol MAC, baseband processor, analog-to-digital and digital-to-analog (ADC/DAC) converters, 2x2 MIMO radio transceiver, and PCI Express interface in an all-cmos device for low power and small form factor applications. The AR9280 implements half-duplex OFDM, CCK, and DSSS baseband processing, supporting up to 130 Mbps for 20 MHz and 300 Mbps for 40 MHz channel operations respectively, and IEEE 802.11a/b/g data rates. Additional features include signal detection, automatic gain control, frequency offset estimation, symbol timing, and channel estimation. The AR9280 MAC supports the 802.11 wireless MAC protocol, 802.11i security, receive and transmit filtering, error recovery, and quality of service (QoS). The AR9280 supports two simultaneous traffic streams using up to two integrated transmit chains and receive chains for high throughput and range performance. Transmit chains combine baseband in-phase (I) and quadrature (Q) signals, convert them to the desired frequency, and drive the RF signal to multiple antennas. Receive chains use an integrated architecture that requires no off-chip intermediate frequency (IF) filters. The frequency synthesizer supports one-mhz steps to match frequencies defined by IEEE 802.11a/b/g/n specifications. 2.3 Antenna Connector There are two SMT Ultra-miniature coaxial connectors (U.FL-R-SMT) on board to support MIMO functionality. 2.4 LED Function WLAN: Signaling supported Slow-rate blinking Active status of Transmission (Tx/Rx/Stby) Off Radio off 2.5 Pin Definition Pin Number Pin Name Pin I/O Type Description 1 WAKE# Output Open Drain active Low signal.
