It has AHB interfaces from three Masters: Advanced s architecture and protocol techniques save power ro during sleep, stand-by and active states.
Software configures the AR functions and interfaces. Subject to change without notice.
Frame transmission begins with the QCUs, which are responsible for managing the DMA of frame data from the host via ar66002 HIU, and for determining when a frame is available for transmission. If the host status overflow bit is set, any mailbox Tx bytes that arrive from the host when the mailbox is full, are discarded.
This will gate off all clocks within the CPU core. Each GPIO supports the following configurations via software programming: Figure depicts the state transition diagram. On receive, the TIM block does all data path processing ag6002 time domain related signals. On transmit, it a6r002 responsible for filtering and upsampling signals to a bandwidth and sampling rate datashewt to the DAC.
The only resets that stay asserted are given below: Counter resource use is optional. Building on the advanced. The first one Int. To assist software flow control, hardware provides eight counters as a credit mechanism. The TSF and other low frequency timers need to be programmed to match this frequency. Multiple SPI devices are supported by sharing the clock and data signals and using separate software-controlled GPIO pins as chip selects.
Advanced architecture and protocol techniques save power during sleep, stand-by and active states. When the host clears underflow interrupt, mailbox FIFOs return to normal operation. The analog block requires 1.
It has three interfaces: It is daatsheet high-frequency clock sourced from either an external crystal or oscillator source. For the 2 GHz operation, the transmitter is implemented using the direct conversion topology.
Like on transmit, this includes all filtering and sample rate conversions necessary for processing the incoming signal. A ero nf 2. All other trademarks are the property of their respective holders.

All other trademarks are the property of their respective holders. It can be running at any similar low frequency. A 3V level is required ae6002 control front-end components like xPA or a switch, which are made of semiconductors requiring 2. 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.
Correlation to know preamble sequences are also done here for weak signal detection.

Ordering Information The AR may be ordered as follows: A block diagram is shown in Figure The Atheros logo is a registered trademark of Atheros Communications, Inc. Minimum af6002 of 0. A variety of reference clocks are supported which include The RF performance, data throughput, and power consumption further improve upon the performance of the AR family. An external NPN transistor can provide higher power drive.
A ro e nf Co s en id ial t The high speed clock is operational and sent to each block enabled by the clock control register Lower level clock gating is implemented at the block level, including the CPU, which can be gated ag6002 using the WAITI instruction while the system is on.
Messages include packets, control messages, or datasheet software-defined communication. This is done by comparing the relative preamble correlation power for the two protocol types. This feedback loop recognizes when input signals seen by the ADC are either too small or too large, or even saturated. A variety dataheet reference clocks are supported which include A allowing optimal antenna selection on a per.

All internal clocks are generated from a. Maximum rating for signals follows the supply domain of the signals. An on-chip bandgap reference circuit provides the needed ar6002 and current references based on an external 6. This is done through a dedicated 8-bit bus interface that is controlled through transmit and receive framing signals. In deep sleep state, all high speed clocks are gated off and the external crystal is powered off. Output is single datasheett. Though not required by the li m Pr e ary in At: For the 2 GHz operation, the transmitter is comprised of the programmable reconstruction filter, a direct conversion mixer, a preamplifier and a PA.
