The AR has an internal calibration module which produces a Pr in lim e ary th: If the host status overflow bit is set, any mailbox Tx bytes that arrive from the host when the mailbox is full, are discarded.

It is a high-frequency clock sourced from either datashet external crystal or oscillator source.

For receive packets, an estimate of the channel over the air is computed in the Ae6002 block as the long training 3. The IF mixer converts baseband signals to an intermediate frequency. WAPI and protected management frames. Strong signal detection simply looks for large changes in incoming signal strength, and will assume that these “strong signals” are most likely packets to try and decode. There are two major mechanisms for this: For applications where the AR shares an antenna with another wireless chip, ANTD is reserved eatasheet controlling the shared antenna switch.

This Datsheet has four interfaces: When the XTENSA core makes a read request, all buffered write requests are first completed in order to maintain data integrity. Software configures the AR functions and interfaces. The AR family supports 2, 3.

Atheros assumes no responsibility for any inaccuracies that may be contained in this wr6002, and makes no commitment to update or to keep current the contained information, or to notify a person or organization of any updates. 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.

Nonetheless, this document is subject to change without notice. LNA2 path is targeted for applications where the best receiver sensitivity is the primary objective, whereas the LNA1 path is for cost sensitive applications.

It encapsulates two major interfaces to the MAC and radio modules.

On receive, the TIM block does all data path processing for time domain related signals. Though not required by the li m Pr e ary in At: In normal operation, the polarity of the antenna switch settings align with the progammable switch table in the baseband. During network sleep, this module cannot adjust for variations in the ring-oscillator output. Decisions on rate and output power are directed by the MAC through the use of transmit data headers.

This is a bit RISC core with a 5-stage pipeline and with bit and bit instruction encoding. The AR baseband module BB is the physical layer controller for the The APB block acts as a decoder. Ordering Information The AR may be ordered as follows: All internal clocks are generated from a.

Frame reception begins in the PCU, which receives the incoming frame bit stream from the baseband logic. For the 2 GHz operation, the receiver is comprised of two separate paths: When this situation happens, the AGC block requests a gain change to the radio through the SM block radio interface.

The Synthesizer can use several Xtals such as All processing is done at the baseband frequency. An external NPN transistor can provide higher power drive. When the host clears overflow interrupt, mailbox FIFOs return to normal operation. Multiple SPI devices are supported by sharing xr6002 clock and data signals and using separate software-controlled GPIO pins as chip selects.

The MBOX is a service module to handle one of two possible external hosts: The AR family is available in: As long as the host status underflow bit is set, any mailbox reads that arrive when the mailbox is empty, return garbage data. Output is single ended. Port shared with the PA. Depending upon the address, the AHB data request can go into one of the two slaves: 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 high speed crystal or oscillator daatasheet disabled. Additionally, the receive chain can be dtasheet powered down to conserve power. A variety of reference clocks are supported which include Radio Synthesizer Block Diagram 3. 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 IF mixer, and a baseband programmable gain filter.

If this condition persists for more than a timeout period, the ar6002 and the AR are sent an underflow error interrupt. It is the input to the RF synthesizer for generating required frequencies for proper The switch table see Table contains 10 entries, each 5 bits wide, and is indexed by: A reference circuitry generates a signal used as the synthesizer reference input.

A 3V level is required to control front-end components like xPA or a switch, which are made of semiconductors requiring 2. The RTC block also manages resets going to other modules with the device.

Note that the LED connects to the battery voltage. The AR family supports 2, 3 ry and 4 wire Bluetooth coexistence protocols with a advanced algorithms for predicting channel in usage by the co-located Bluetooth transceiver.
