Transmitter RF Output for Cellular Band (800MHz to 1000MHz)—for both FM
and digital modes. This open-collector output requires a pull-up inductor to
the supply voltage, which may be part of the output matching network and
may be connected directly to the battery.
No Connection. Make no connection to these pins.
Transmitter RF Output for PCS Band (1700MHz to 2000MHz). This open-
collector output requires a shunt inductor to the supply voltage. The pull-up
inductor may be part of the output matching network and may be connected
directly to the battery.
Open-Collector Output Indicating Lock Status of the IF and/or the RF PLLs.
Requires a pull-up resistor. Control using configuration register bit LD_MODEO,
LD_MODE1.
Power Supply
Digital Input. A logic low on IDLE shuts down everything except the RF PLL
and associated registers. A small RC lowpass filter may be used to prevent
digital noise.
Supply Pin for the Upconverter Stage. V
ground as close to the pin as possible. The ground vias for the bypass
capacitor should not be shared by any other branch.
Digital Input. A logic low on TXGATE shuts down everything except the RF
PLL, IF PLL, IF VCO, and serial bus and registers. This mode is used for
gated transmission.
Differential Inputs to the RF Upconverter. These pins are internally biased to
1.5V. The input impedance for these ports is nominally 400Ω differential. The
IF filter should be AC-coupled to these ports. Keep the differential lines as
short as possible to minimize stray pick-up and shunt capacitance.
Differential Inputs to the RF Upconverter. These pins are internally biased to
1.5V. The input impedance for these ports is nominally 400Ω differential. The
IF filter should be AC-coupled to these ports. Keep the differential lines as
short as possible to minimize stray pick-up and shunt capacitance.
Bias Resistor Pin. RBIAS is internally biased to a bandgap voltage of 1.18V. An
external resistor or current source must be connected to this pin to set the bias
current for the upconverters and PA driver stages. The nominal resistor value is
16kΩ. This value can be altered to optimize the linearity of the driver stage.
Input Pins from the 3-Wire Serial Bus (SPI/QSPI/MICROWIRE compatible).
An RC filter on each of these pins may be used to reduce noise.
