Differential Tank Pins for the High-Frequency IF VCO. These pins are internally
biased. VCO_SEL = 1 selects this IF VCO.
No Connection. Make no connection to these pins.
Reference Frequency Input. REF is internally biased and must be AC-cou-
pled to the reference source. This is a high-impedance port (25kΩ
Supply for the IF Charge Pump. This supply can differ from the system V
Bypass as close to the pin as possible. The bypass capacitor must not share
its vias with any other branches.
High-Impedance Output of the IF Charge Pump. Connect to the tune input of
the IF VCOs through the IF PLL loop filter. Keep the line from IFCP to the tune
input as short as possible to prevent spurious pick-up, and connect the loop
filter as close to the tune input as possible.
Supply Pin for Digital Circuitry. Bypass as close to the pin as possible. The
bypass capacitor must not share its vias with any other branch.
High-Impedance Output of the RF Charge Pump. Connect to the tune input
of the RF VCOs through the RF PLL loop filter. Keep the line from this pin to
the tune input as short as possible to prevent spurious pickup, and connect
the loop filter as close to the tune input as possible.
Supply for the RF Charge Pump. This supply can differ from the system V
Bypass as close to the pin as possible. The bypass capacitor must not share
its vias with any other branches.
RF PLL Input. AC-couple this port to the RF VCO. RFPLL is internally biased.
High-band RF LO Input Port. AC-couple to this port.
Low-band RF LO Input Port. AC-couple to this port.
Isolation GND. No internal connection. Connect to PC board ground plane for
better isolation.
Transmitter RF Output for PCS Band (1700MHz to 2000MHz). This open-col-
lector output requires a pullup inductor to the supply voltage. The pullup
inductor may be part of the output matching network and can be connected
directly to the battery. For split band PCS application, use RFH1 for the
1850MHz–1880MHz range.
DC and AC GND Return for the IC. Connect to PC board ground plane using
multiple vias.
