Differential Tank Pins for the High-Frequency IF VCO. These pins are internally
biased to +1.6V.
No Connection. Leave these pins floating.
Reference Frequency Input. REF is internally biased to V
be AC-coupled 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 pickup, 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.
High-band RF LO Input Port. AC-couple to this port.
Low-band RF LO Input Port. AC-couple to this port.
Ground. Connect to PC board ground plane.
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 may be connected
directly to the battery.
DC and AC GND Return for the IC. Connect to PC board ground plane using
multiple vias.
