The DAC has a period of samples with a configurable number of clock cycles per sample.
Frame transmission begins with the QCUs, which are responsible for managing the DMA of frame data from the host via the HIU, and for determining when a frame is available for transmission. The others are hardware interrupts for various configurations.
A variety of reference clocks are supported which include The MBOX is a service module to handle one of two possible external hosts: Correlation to know preamble sequences are also done here for weak signal detection.
Nonetheless, this document is subject to change without notice. The Atheros AR is the 2nd generation of the. The first one Int. Strong signal detection simply looks for large ar66002 in incoming signal strength, and will assume that these “strong signals” are most likely packets to try and decode.
An on-chip bandgap reference circuit provides the needed voltage and current references based on an external 6. It then begins communicating with this host. A lower voltage, down to 3. The AR baseband module BB is the physical layer controller for the The I and Q signals are low-pass filtered and amplified by the baseband programmable gain filter controlled by digital logic.
This is used mainly for register accesses. The SOC clock comes from a clock divider module which divides the base clock by a programmable value. For the 2 GHz operation, the transmitter is implemented using the direct conversion topology. Minimum clearance of 0.

The PCU also handles processing responses to the transmitted frame and reporting the transmission attempt results to the DCU. For the 2 GHz operation, the transmitter is comprised of the programmable satasheet filter, a direct conversion mixer, a preamplifier and a PA. It is the input to the Datasheet synthesizer for generating required frequencies for proper A allowing optimal dqtasheet selection on a per. In deep sleep mode, the voltage supply to the SOC block, which includes the CPU, can be scaled down to save leakage power.
Port shared with the PA. The AR family supports 2, 3 and 4 wire Bluetooth coexistence protocols with advanced algorithms for predicting channel usage by the co-located Bluetooth transceiver. The Synthesizer can use several Xtals such as For applications where the AR shares an antenna with another wireless chip, ANTD is reserved for controlling the shared antenna switch.
As long as the host status underflow bit is set, any mailbox reads that arrive when the mailbox is empty, return garbage data. Pin Descriptions This section contains a listing of the signal datasheeh see Table for the BGA package pin outs.
Software must then either resynchronize flow control state or reset the AR to recover. The AR family is available in: The Atheros logo is a registered trademark of. In deep sleep state, all high speed clocks are gated off and the external crystal is powered off. Radio The AR transceiver consists of four major functional blocks see Figure Datashwet this situation happens, the AGC block requests a gain change to the radio through the SM block radio interface.
System includes external PA.

Additionally, the receive chain can be digitally powered down to conserve power. Because the ADC dynamic range does not span all possible input power levels, an automatic gain control feedback loop is designed into the radio and datahseet receive 24 24? 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.
The Atheros logo is a registered ar602 of Atheros Communications, Inc. The Viterbi soft-decision decoder is contained within the VIT block, and is responsible for descrambling, deinterleaving, and decoding the symbols from the FFT. LNA2 path is targeted for applications where the best receiver sensitivity is the primary objective, whereas the LNA1 path is for cost sensitive applications. The outputs of the DAC are low pass filtered through an on-chip reconstruction filter to remove spectral images and out-of-band quantization noise.
For the 5 GHz operation, the transmitter is implemented using the sliding IF topology. ar66002
