Description
Power Supply. Power supply voltage range is 4.75 V to 5.25 V. Each power supply pin should be decoupled
with a 100 pF capacitor and a 0.1 μF capacitor located close to the pin.
Connect a resistor from this pin to a +5 V supply to adjust IIP3. Normally leave open.
No Connection.
LO Driver Enable. Together with Pin 16 (PLL_EN), this digital input pin determines whether the LOP and LON
pins operate as inputs or outputs. LOP and LON become inputs if the PLL_EN pin is low or if the PLL_EN pin is
set high with the PLEN bit (DB6 in Register 5) set to 0. LOP and LON become outputs if either the LODRV_EN pin
or the LDRV bit (DB3 in Register 5) is set to 1 while the PLL_EN pin is set high. The external LO drive frequency
must be 1× LO. This pin should not be left floating.
Local Oscillator Input/Output. The internally generated 1× LO is available on these pins. When internal LO
generation is disabled, an external 1× LO can be applied to these pins.
VCO Control Voltage Input. This pin is driven by the output of the loop filter. The nominal input voltage range
on this pin is 1.5 V to 2.5 V.
Decoupling Node for the VCO LDO. Connect a 100 pF capacitor and a 10 μF capacitor between this pin and
ground.
Exposed Paddle. The exposed paddle should be soldered to a low impedance ground plane.
