Page 1 of 7 Last printed 7/4/2003 6:05 PM Askey 802.11a/b/g, 802.11b/g WLAN card Functional Description The Askey 802.11a/b/g, 802.11b/g WLAN card Designs are based on Atheros AR5002X chip set which implements IEEE 802.11a, IEEE 802.11b, and IEEE 802.11g WLAN solutions or the AR5002G chipset for IEEE 802.11b/g-only solutions. The chipsets consist of the following: z AR5212An all-CMOS, IEEE 802.11a/802.11b/802.11g MAC/baseband processor, and CardBus/PCI bus interface. z AR5112 Radio-on-a-Chip (RoC) An all-CMOS IEEE 802.11a/802.11b/802.11g, single-chip radio transceiver that converts RF signals to the baseband range for use by the AR5212. The AR5112 offers fully integrated transmitter, receiver, and frequency synthesizer functions; eliminating the need for external voltage controlled oscillators (VCOs) and surface acoustic wave (SAW) filters. z AR2112 Radio-on-a-Chip (RoC) An all-CMOS IEEE 802.11b/802.11g, single-chip radio transceiver that converts RF signals to the baseband range for use by the AR5212. The AR2112 offers fully integrated transmitter, receiver, and frequency synthesizer functions; eliminating the need for external voltage controlled oscillators (VCOs) and surface acoustic wave (SAW) filters. When combined into a single design, the AR5002X (AR5112 and AR5212) chip set enables a low-cost, compact multi-mode solution that easily fits on a PC Card or Mini PCI design. For IEEE 802.11g-only implementations, the WLAN card may be used by not populating the IEEE 802.11a radio section, replacing the AR5002X chip set with a AR5002G (AR2112 and AR5212) chip set. By doing this, a single PCB may be used for triple band designs, and single band designs. AR5002 STA Block Diagram The AR5002X chipset provides a highly integrated IEEE 802.11a, IEEE 802.11b, and IEEE 802.11g solution, as shown by the block diagram in Figure 1-1. Page 2 of 7 Last printed 7/4/2003 6:05 PM Figure 1-1. AR5002 STA Radio Block Diagram The AR5212 is the origin and destination for all the front-end signals. Both transmit (Tx) and receive (Rx) signals are transferred by the AR5112 to either a 5 GHz front-end, or to a 2.4 GHz front end. The 5 GHz and the 2.4 GHz front ends share a single set of antennae, dual band switch, Rx diplexer, Tx diplexer/low pass filter, coupler, and power detect circuitry. The 5 GHz transmit signal is boosted with an output booster (OPB). The OPB drives a diplexer and a coupler/detector (PDET) assembly. The diplexers function is to combine the 5 GHz and 2.4 GHz signals, while the coupler/ detectors function is to sample the transmit signal and rectify it. The rectified signal is proportional to the output power and is used for power leveling and control. The RF transmit signal then passes through a dual band switch. This switch enables the connection of the input to either one of the two antennae. The 5 GHz receive signal is transferred in a reverse order from the antennae through the switch and receive diplexer. It is then boosted using a low noise amplifier (LNA) and fed back into the AR5112. The transmit and receive 2.4 GHz signals follow a similar path as the 5 GHz signals in the 2.4 GHz front-end. CardBus/PCI Interface The CardBus/PCI interface of the AR5212 is PCI 2.3 and PC Card 7.1 compatible. In the WLAN card design, this interface seamlessly connects to Page 3 of 7 Last printed 7/4/2003 6:05 PM the CardBus or Mini PCI interface provided by the host. MAC/Baseband Processor (AR5212) The AR5212 is a highly integrated chip containing a CardBus/PCI interface, media access control (MAC) and a baseband processor (PLCP/PHY). The AR5212 runs on 2.5 V (digital and analog) core and 3.3 V I/O, and is packaged in a 15x15x1.5 mm 196 plastic ball grid array (PBGA). 40 MHz Crystal The 40 MHz crystal provides the core clock for the AR5212 and ARx112, (AR5112/AR2112). This crystal is attached to the ARx112, which then internally forms an oscillator. The ARx112 then provides the output of the oscillator to its internal frequency synthesizer, and to the AR5212. The maximum frequency tolerance allowed by the IEEE 802.11a standard is +/ 20 ppm. Therefore, the crystal device needs to meet this requirement over all operating conditions. Atheros recommends a crystal device with an overall tolerance of 18 ppm that includes initial tolerance, tolerance over operating temperature range and aging tolerance. The crystal device used in the Reference Design is calibrated at 19.5 pF load. When designing the crystal circuit, care should be taken to include the board stray and other capacitances, such as those inherent with the oscillator circuits, in the overall calculation of the load capacitance. A significant shift in frequency can occur if the overall load capacitance presented to the crystal device is not the same as what the crystal was cut for. Excessive load capacitance on the crystal circuit, compared to the actual load that the crystal was designed for, shifts the frequency down. Conversely, lower load capacitance causes an increase in the frequency of the circuit. When the final circuit boards are available, the overall crystal circuit load capacitance should be calibrated by requesting known frequency crystals at a particular load from the crystal vendor. RF Front End Section This section provides information and design guidelines for the transmit and receive paths between the antennae and the ARx112. General Guidelines All RF, Rx, and Tx traces are to be 50 unless otherwise noted, and must have no sharp bends (90 ) unless otherwise noted. Atheros recommends that all RF components, traces, and the ARx112 be on the same side of the board. Vias should be avoided in the RF traces as much as possible. Do not use any test points on any RF trace or component. Minimize lengths of all RF traces because FR4 material is inherently lossy at RF frequencies. Minimizing the trace lengths reduces the overall signal loss. It is more important to keep the Tx path short than it is to keep the Rx path short. A loss in …
