Description
Input from the external network processor. The rising edge of TX PE
places the transmitter into an active state. The falling edge of TX PE
indicates the end of transmission.
When active (value '1'), the receiver is powered up and CCA circuitry is
active.
Master clock. This should be a 44MHz for IEEE802.11b and is used to
generate other internally used clocks.
Indicates that the chip is ready to accept data from the MAC for Tx.
Indicates that the chip is ready to deliver data to the MAC from Rx.
Output from 2.2V internal voltage regulator for digital sections of
RF3000. This pin should not be connected to anything.
Ground signal for digital power.
Clear channel assessment per IEEE802.11b standard. “1” indicates
“clear”.
LNA gain select. “1” indicates “high gain”.
TX data stream input.
Data clock for TX and RX data.
RX data stream output.
In SPI mode this pin serves as serial port chip select.
Serial port clock. This clock is used for SPI mode.
In SPI mode this pin serves as CDIN input.
In SPI mode this pin serves as CDOUT output.
Analog receive variable gain control output: 1.2V to 2.0V.
Not connected.
Analog I input.
Analog Q input.
DC power for analog sections 3.3V.
Ground signal for analog power.
Analog I output: 1.6V to 1.8V.
Analog Q output: 1.6V to 1.8V.
Analog voltage for transmitter variable gain control: 1.2V to 2.0V.
Antenna selection signal for diversity receiver.
Pin='1' chip reset.
Pin='0' standard operation.
Reference voltage for internal data converters.
