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/D isable.
