This is used mainly for register accesses. The closed-loop power control can be based on an on-chip or off-chip power detector. It is also possible to hold the CPU in reset until the host clears an internal register.

The IF mixer converts baseband signals to an intermediate frequency. Multiple I2C devices with different device addresses are supported by sharing the two-wire bus. All processing is done at the baseband frequency. During network sleep, this module cannot adjust for variations in the ring-oscillator output.

The following nomenclature is used for signal names: For receive packets, an estimate of the channel over the air is computed in the FFT block as the long training 3.

It can be running at any similar low frequency. The Atheros AR is the 2nd generation of the. Minimum clearance of 0. This module can buffer up to 4 write requests. Depending upon the address, the AHB data request can go into one of the two slaves: Functional operation under these conditions, or at any other condition beyond those indicated in the operational sections of this document, is not recommended.

In case the output from the calibration module is not accurate enough, the AR does have the capability a6r002 use an external low-speed clock source. See the Host Interface chapter for a table listing interface type options.


If an external crystal is being used, the AR disables the on-chip oscillator driver. All other trademarks are the property of their respective holders. For both 5G and 2G paths, mixers down convert the signal to baseband in-phase I and quadrature-phase Q signals. The flow control of the four mailboxes must be managed by software. The BB needs this fundamental clock together with several divided versions of it. AR chips li Pr e in m ary th: Subject to change without notice.

Advanced s architecture and protocol techniques save power ro during sleep, stand-by and active states. The receiver is tuned to 2. It has AHB interfaces from three Masters: LNA2 path is targeted for applications where the best receiver sensitivity is the primary objective, whereas the LNA1 path is for cost sensitive applications. A reference circuitry generates a signal used as the synthesizer reference input. Software configures the AR functions and interfaces. When this situation happens, the AGC block requests a gain change to the radio through the SM block radio interface.

The APB block acts as a decoder. Frame reception begins in the PCU, which receives the incoming frame bit stream from the baseband logic. 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.

Table shows pin settings for mode configuration, sampled during reset. An external NPN transistor can provide higher power drive. The MBOX has two interfaces: The AR requires 3 power levels, 1. Atheros AR Datasheet Preview. All interrupts can be masked by control datsheet.


Messages include packets, control messages, or any software-defined communication. A f nBlock 3. Figure depicts the state transition diagram. It is responsible for modulating data packets in the transmit datadheet, and detecting and demodulating data packets in the receive direction. Atheros assumes no responsibility for any inaccuracies that may be contained in this document, and makes no commitment to update or daatsheet keep current the contained information, or to notify a person or organization of any updates.

This will gate off all clocks within the CPU core.

The MBOX is a service module to handle one of two possible external hosts: The switch table see Table contains 10 entries, each 5 bits wide, and is indexed by: A allowing optimal antenna selection on a per. This external clock source can be used as the sleep clock instead of the calibration module output.

The SOC clock comes from a clock divider module which divides the base clock by a programmable value. Figure shows the host interface address map. Radio Functional Block Diagram 3. This is done through a dedicated 8-bit bus interface that is controlled through transmit and receive framing signals. This is done by comparing the relative preamble correlation power for the two protocol types.
