All interrupts can be masked by control registers. A ero nf 2. If there are any radio impairments that need to be corrected carrier leak, etc. AR chips li Pr e in m ary th: 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.

It has three interfaces: Reset and Power Cycle Timing 30 30? The n RF performance, data throughput, and power o consumption further improve upon the C performance of the AR family. When the host clears underflow interrupt, mailbox FIFOs return to normal operation. Decisions on rate and output power are directed by the MAC through the use of transmit data headers.

See the AR block diagram on page dafasheet.

When this situation happens, the AGC block requests datazheet gain change to the radio through the SM block radio interface. The AR family is available in: WAPI and protected management frames. Before symbols can be decoded, this channel estimate is inverted and applied to the incoming frequency symbols for channel correction.

By default, this value is 8. Receiver Characteristics for 2. Radio The AR transceiver consists of four major functional blocks see Figure On receive, the TIM block does all data path processing for time domain related signals. Its internal logic and boot code are designed to detect the presence of an external host and to automatically begin communicating with that host.

The host reads the ready bit and can now send function commands to the AR A block diagram is shown in Figure Weak signal detection will correlate against known preamble sequences when gain changes are not occurring. Its inputs consist of sleep requests from these modules and its outputs consists of clock enable and power signals which are used to gate the clocks going to these modules. 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.

Transmitter Characteristics for 2. The analog block requires 1. The PLL output is programmable but it will usually run at one of only two frequencies: 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.

The host then reads interface registers to determine the type of function that the AR supports. 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 baseband receive 24 24? The first one Int.

AR System Block Diagram. Functional operation under these conditions, or at any other condition beyond those indicated in the operational sections of this document, is not recommended.

C performance of the AR family. Data requests to the VMC are generally high-speed memory requests, while requests to the APB block are primarily meant for register access. Subject to change without notice. If not, an internal regulator can be used. Nonetheless, this document is subject to change without notice. An external NPN transistor can provide higher power drive.

Ordering Information The AR may be ordered as follows: Each GPIO supports the following configurations via software programming: Boot code in the ROM first detects the presence of an external host.
