An on-chip PLL creates the appropriate clock frequency for digital logic.
AR datasheet & applicatoin notes – Datasheet Archive
Typically, this crystal input is only available when the system is in the normal operating state and is shut down during network sleep. For applications where the AR shares an antenna with another wireless chip, ANTD is reserved for controlling the shared antenna switch. Once the DCU gains access to the channel, it passes the frame to the PCU, which manages the final details of sending the frame to the baseband logic.
The flow control of the four mailboxes must be managed by software. Maximum rating for signals follows the supply domain of the signals.
If this condition persists for more than a timeout period, the host and the AR are sent an underflow error interrupt. Hence the calibration module can adjust for process and temperature variations only when the system is in the normal operating state.

It is also possible to hold the CPU in reset until the host clears an internal register. The Atheros AR is the 2nd generation of the.
Counter resource use is optional. Messages include packets, control messages, or any software-defined communication. Port shared with the PA. For the 2 GHz operation, the transmitter is comprised of the programmable reconstruction filter, a direct conversion mixer, a preamplifier and a PA. The BB needs this fundamental clock together with several divided dataseet of it.
Synthesizer Composite Characteristics for 2. Transmitter Characteristics for 2.
During network sleep, this module cannot adjust for variations in the ring-oscillator output. It has AHB interfaces from three Masters: If an external crystal xatasheet being used, the AR disables the on-chip oscillator driver. Absolute maximum ratings are those values beyond which damage to the device can occur. As long as the host status underflow bit is set, any mailbox reads that arrive when the mailbox is empty, return garbage data.

The core has been configured with several clock gating elements which scale down clocks to circuitry that is not changing. 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 which can be accessed by the host.
Typically, this DCU is the one associated with beacon-gated frames i. Building on the advanced AR Features performance and features of the AR family, the compact size and low power consumption of this single chip design make it an ideal vehicle for adding WLAN to hand-held and other battery-powered consumer electronic devices.
All interrupts can be masked by control registers. Radio Synthesizer Block Diagram 3. Note that the LED connects to the battery voltage.
LNA2 path is targeted for applications where the best receiver sensitivity is the primary objective, whereas the LNA1 path is for cost sensitive applications. On power up or 22 22?

The first one Int. When the AR is ready to receive commands from the host, it will set the function ready bit. Radio The AR transceiver consists of four major functional blocks see Figure Figure shows the host interface address map. 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. The MBOX is a service module to handle one of two possible external hosts: In case the output from the calibration module is not accurate enough, the AR does have the capability to use an external low-speed clock source.
Advanced s architecture and protocol techniques save power datassheet during sleep, stand-by datawheet active states. If the host status overflow bit is set, any mailbox Tx bytes that arrive from the host when the mailbox is full, are discarded. Advanced architecture and protocol techniques save power during sleep, stand-by and active states.
