This CPU has four interfaces: 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.

WAPI and protected management frames. It can be running at any similar low frequency. Correlation to know preamble sequences are also done here for weak signal detection.
Nonetheless, this document is subject to change without notice. Building on the advanced. The Atheros AR is the 2nd generation of the. The VMC contains arbiters to serve these three interfaces on a first-come-first-serve basis.
This process reduces potential latency penalties by running both receivers in parallel while the detection state machine AGC tries to decide which type of protocol the incoming packet has been modulated with. If an external crystal is being used, the AR disables the on-chip oscillator driver. The host and AR CPUs can read and write these counters using ordinary writes or atomic operations.
Atheros reserves the right to make changes, at any time, to improve reliability, function or design and to attempt to supply the best product possible. For the 2 GHz operation, the transmitter is comprised of the programmable reconstruction filter, a direct conversion mixer, a preamplifier and a PA. On transmit, it is responsible for filtering and upsampling signals to a bandwidth and sampling rate appropriate to the DAC. Radio Synthesizer Block Diagram 3.

In deep sleep mode, the voltage supply to the SOC block, which includes the CPU, can be scaled down to save leakage power. In addition, software may operate the SI in either polling or interrupt mode.
A lower voltage, down to 3. Advanced s architecture and protocol techniques save power ro during sleep, stand-by and active states. The IF mixer converts baseband signals to an intermediate frequency. The analog block requires 1. Instead, there is now a ring oscillator which produces a clock that is nominally running at 2 MHz, but this can depending on process and temperature.

The digital core runs off of 1. Depending upon the address, the AHB data request can go into one of the two slaves: The switch table see Table contains 10 entries, each 5 bits wide, and is indexed by: The AR family includes a highly integrated, front-end module Power Amplifier, Low-Noise Amplifier and RF switchenabling low-cost designs with minimal external components. 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.
All other trademarks are the property of their respective holders. The receiver is tuned to 2. The least significant bit of the register is ANTA. LNA2 path is targeted for applications where the best receiver sensitivity is the primary xatasheet, whereas the LNA1 path is for cost sensitive applications.
A variety of reference clocks are supported which include The I and Q signals are low-pass filtered and amplified by the baseband programmable gain filter controlled by digital logic. All other trademarks are the property of their respective holders.
Its inputs consist of sleep requests from these modules and its outputs consists of clock enable and power signals which are used to gate datzsheet clocks going to these modules. The CPU may continue to be held in reset under some circumstances until its reset is cleared by an external pin or when the host clears a register.

For the 5 GHz operation, the transmitter is implemented using the sliding IF topology. By default, this value is 8.
For the 5 GHz operation, the receiver is comprised of a low noise amplifier LNA followed by a variable gain amplifier VGAa radio frequency RF mixer, an intermediate frequency Datzsheet mixer, and a baseband programmable gain filter. Ordering Information The AR may be ordered as follows: For the 2 GHz operation, the receiver is comprised of two separate paths: The RF performance, data throughput, and power consumption further improve upon the performance of the AR family.
See Figure for details. It is responsible for modulating data packets in the transmit direction, and detecting and demodulating data packets in the receive direction. See the AR block diagram on page 1.
Figure depicts the state transition diagram. Software is responsible for mapping the eight priority levels called for in the This external clock source can be used as the sleep clock instead of the calibration module output.
The AR family supports 2, 3. The Synthesizer can use several Xtals such as Table aar6002 pin settings for mode configuration, sampled during reset.
