AR6002 Datasheet PDF
A separate configuration address space for the baseband block is written through the MAC block, as the baseband block ar66002 not directly connected to the AHB bus. Radio Synthesizer Block Diagram 3. The host reads the ready bit and can now send function commands datasgeet the AR The others are hardware interrupts for various configurations. Once the DCU gains access to the channel, it passes the frame to the PCU, which manages the final details of sending the frame to the baseband logic.
Darasheet pdf – http: Data requests to the VMC are generally high-speed memory requests, while requests to the APB block are primarily meant for register access.
The DAC has a period of samples with a configurable number of clock cycles per sample. Atheros assumes no responsibility for any inaccuracies that may be contained in this document, and makes no commitment to update or to keep current the contained information, or to notify a person or organization of any updates. The baseband to radio interface is a low-latency shift control interface that allows the baseband module to quickly and autonomously adjust radio settings to reflect the current packet sizing and direction flow.
Advanced s architecture and protocol techniques save power ro during sleep, datasueet and active states. The IF mixer converts baseband signals to an intermediate frequency. The Viterbi soft-decision decoder is contained within the VIT block, and is responsible for descrambling, deinterleaving, and decoding the datsheet from the FFT.
The core has been configured with several clock gating elements which scale down clocks to circuitry that is not changing. The host and AR CPUs can read and write these counters using ordinary writes or atomic operations. See Figure for details.
Building on dwtasheet advanced AR Features performance and features of the AR family, the compact size and low power consumption of this single chip design ad6002 it an ideal vehicle for adding WLAN to hand-held and other battery-powered consumer electronic devices. Depending upon the address, the APB request can go to one of the eight places listed below: Correlation to know preamble sequences are also done here for weak signal detection.
All processing is done at the baseband frequency. An on-chip PLL creates the appropriate clock frequency for digital logic. The counters may count messages, memory buffers, packets, or any unit that software defines.
Datasheet for Qualcomm Atheros AR6002
The PCM controls all power and isolation control signals for the entire chip. The high speed crystal or oscillator is disabled. Virtual and Physical Memory Mapping 1. When the XTENSA core makes a read request, all buffered write requests datashfet first completed in order to maintain data integrity.
In case the output from the calibration module is not accurate enough, the AR does have the capability to use an external low-speed clock source. Software configures the AR functions and interfaces.
The BB needs this fundamental clock together with several divided versions of it. On receive, the TIM block does all data path processing for daasheet domain related signals. Counter resource use is optional.

All interrupts can be masked by control registers. Multiple SPI devices are supported by sharing the clock and datasheet signals and using separate software-controlled GPIO pins as chip selects. For the 2 GHz operation, the receiver is implemented using the direct conversion topology. The digital core runs off of 1.
