Transmit and Receive Switch Control: This is a complement for TRSW+.
1:RX
0:TX
Output Pin as Transmit (TX) In-phase Digital Data of the Philips Chipset. This
function is valid on Tx digital mode (AnalogPhy = Digital on EEPROM writer
program).
Transmit PA Power Enable: Assert high when starting transmission.
Transmit (TX) Quadrature Digital Data of Philips Chipset. This function is valid
on Tx digital mode (AnalogPhy = Digital on EEPROM writer program).
Output Pin as TX/RX Control:
1:RX
0:TX
Receive (Rx) In-phase Analog Data: Positive path of differential pair.
Receive (Rx) In-phase Analog Data: Negative path of differential pair.
Receive (Rx) Quadrature-phase Analog Data: Positive path of the differential
pair.
Receive (Rx) Quadrature-phase Analog Data: Negative path of the differential
pair.
Received Signal Strength Indication: To internal ADC.
Transmit Power Detect: To internal ADC which detects transmit power.
Reference Voltage for ADC & DAC
Transmit (Tx) In-phase Analog Data: Positive path of differential pair. This
function is valid on Tx digital mode (AnalogPhy = Digital on EEPROM writer
program).
Transmit (Tx) In-phase Analog Data: Negative path of differential pair. This
function is valid on Tx digital mode (AnalogPhy = Digital on EEPROM writer
program).
Transmit (Tx) Quadrature-phase Analog Data: Positive path of the differential
pair. This function is valid on Tx digital mode (AnalogPhy = Digital on
EEPROM writer program).
Transmit (Tx) Quadrature-phase Analog Data: Negative path of the differential
pair. This function is valid on Tx digital mode (AnalogPhy = Digital on
EEPROM writer program).
Not used in Philips RF chipset
Not used in Philips RF chipset
3-wire Bus Clock: The serial clock output
3-wire Bus Data: Serial data output
3-wire Bus Enable: Enable serial port output
Not used in the Maxim RF chipset.
Not used in the Maxim RF chipset.
LNA Gain Select Logic Output: Logic high for LNA high-gain mode, logic low
for LNA low- gain mode.
Antenna Select +: The antenna selects signal changes state as the receiver
switches from antenna to antenna during the acquisition process in the antenna
diversity mode. This is a complement for ANTSEL- for differential drive of
antenna switches.
Antenna Select -: The antenna selects signal changes state as the receiver
switches from antenna to antenna during the acquisition process in the antenna
diversity mode. This is a complement for ANTSEL+ for differential drive of
antenna switches.
Not used in the Maxim RF chipset.
Not used in the Maxim RF chipset.
Output Pin as VCO VCC Power Enable/Disable.
