Description
Input/Complementary In-Phase Input to the Receive Filter Stage.
Receiver Filter Power Supply. This voltage ranges from 3.15 V to 3.45 V. Decoupling capacitors to the
analog ground plane should be placed as close as possible to this pin. RxV
value as AV
Buffered Local Oscillator Output. These outputs are used to provide the LO for the external RF
demodulator. These require an RF choke to AV
demodulator.
Analog Ground. This is the ground return path of analog circuitry.
Digital Ground.
PLL Reference Input. This is a CMOS input with a nominal threshold of V
input resistance of 100 kΩ (see Figure 13). This input can be driven from a TTL or CMOS crystal
oscillator, or it should be ac-coupled.
Digital Power Supply. This voltage ranges from 3.15 V to 3.45 V. Decoupling capacitors to the digital
ground plane should be placed as close as possible to this pin. DV
This pin supplies the voltage to the charge pump. If the internal VCO is used, it should equal AV
and DV
Charge Pump Output. When enabled, this pin provides ±I
drives the external VCO.
A capacitor connected to this pin is used to roll off noise from the VCO. It should be decoupled to
AGND with a value of 10 nF. The output voltage on this part is proportional to temperature. At
ambient temperature, the voltage is 2.0 V.
A capacitor connected to this pin is used to roll off noise from the VCO. It should be decoupled to
AGND with a value of 10 nF.
