AR6002 Datasheet PDF

The TSF and other low frequency timers need to be datwsheet to match this frequency. The AR family is available in: See Figure for details. The digital core runs off of 1.

It encapsulates two major interfaces to the MAC and radio modules. In case the output from the calibration module is not accurate enough, the AR does have the datasheft to use an external low-speed clock datasheer. Data requests to the VMC are generally high-speed memory requests, while requests to the APB block are primarily meant for register access. Though not required by the li m Pr e ary in At: Additionally, the receive chain can be digitally powered down to conserve power.

For this, it uses the highspeed crystal input as the golden clock.

It has three interfaces: The VMC contains arbiters to serve these three interfaces on a first-come-first-serve basis. The AR family supports 2, 3 ry and 4 wire Bluetooth coexistence protocols with a advanced algorithms for predicting channel in usage by datssheet co-located Bluetooth transceiver.

For the 5 GHz operation, the transmitter is implemented using the sliding IF topology. See the Host Interface chapter for a table listing interface type options. This is done through a dedicated 8-bit bus interface that is controlled through transmit and receive framing signals. It can be running at any similar low frequency. Table shows pin settings for mode configuration, sampled during reset. Atheros assumes no dtaasheet 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.


The high speed crystal or oscillator is disabled.

The host reads the ready bit and can now send function commands to the AR Multiple I2C devices with different device addresses are supported by sharing the two-wire bus. When a detection flag is set, coarse timing acquisition and frequency correction are done in the TIM block, as these functions are performed on data before translation into frequency domain signals in the FFT.

If this condition persists for more than a timeout period, the host and the AR are sent an underflow error interrupt. The analog block requires 1. When the host clears overflow interrupt, mailbox FIFOs return to normal operation.

Pin Descriptions This section contains a listing of the signal descriptions see Table for the BGA package pin outs. The AR can handle only one of these hosts at any given time. If the host status overflow bit is set, any mailbox Tx bytes that arrive from the host when the mailbox is full, are discarded. A separate configuration address space for the baseband block is written through the MAC block, as the baseband block is not directly connected to the AHB bus.

When this situation happens, the AGC block requests a gain change to the radio through the SM block radio interface. On transmit, it is responsible for filtering and upsampling signals to a bandwidth and sampling rate appropriate to the DAC. Receiver Characteristics for 2. It has AHB interfaces from three Masters: The flow control of the four mailboxes must be managed by software. These frequency bins are used for OFDM symbol decoding. This clock is completely independent from those mentioned above and is driven by the external host to communicate with the AR This clock drives the interface logic as well as a few registers ddatasheet can be accessed by the host.

The first one Int. This is a bit RISC core with a 5-stage pipeline and with bit and bit instruction encoding. For the 2 GHz operation, the receiver is implemented using the direct conversion topology. The MBOX has two interfaces: The SOC clock comes from a clock divider module which divides the base clock by a programmable value. Atheros reserves the right to make changes, at any time, datasheey improve reliability, function or design and to attempt to supply the best product possible.

Subject to change without notice. Each GPIO supports the following configurations via software programming: All processing datassheet done at the baseband frequency.

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. If not, an internal regulator can be used. The host and AR CPUs can read and write these counters using ordinary writes or atomic operations.

Atheros AR Datasheet Preview. Hence the calibration module can adjust for process ratasheet temperature variations only when the system is in the normal operating state. This CPU has four interfaces: The APB block acts as a decoder. There are four scenarios where the CPU Reset can be asserted:
