Description
Power Supply for the 3.3 V LDO. 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.
Decoupling Node for the 3.3 V LDO. Connect a 0.1 µF capacitor between this pin and ground.
Charge Pump Output Pin. Connect to VTUNE through the loop filter.
Ground. Connect these pins to a low impedance ground plane.
Charge Pump Current. The nominal charge pump current can be set to 250 µA, 500 µA, 750 µA, or 1 mA
using Bits[DB11:DB10] in Register 4 and by setting Bit DB18 to 0 (internal reference current). In this mode,
no external R
externally adjusted according to the following equation:
Reference Input. Nominal input level is 1 V p-p. Input range is 12 MHz to 160 MHz.
Multiplexer Output. This output can be programmed to provide the reference output signal or the lock detect
signal. The output is selected by programming Bits[DB23:DB21] in Register 4.
Decoupling Node for the 2.5 V LDO. Connect a 0.1 µF capacitor between this pin and ground.
Power Supply for the 2.5 V LDO. 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.
Serial Data Input. The serial data input is loaded MSB first; the three LSBs are the control bits.
Serial Clock Input. The serial clock input is used to clock in the serial data to the registers. The data is latched
into the 24-bit shift register on the CLK rising edge. The maximum clock frequency is 20 MHz.
Load Enable. When the LE input pin goes high, the data stored in the shift registers is loaded into one of the
eight registers. The relevant latch is selected by the three control bits of the 24-bit word.
PLL Enable. Switch between internal PLL and external LO input. When this pin is logic high, the mixer LO is
automatically switched to the internal PLL and the internal PLL is powered up. When this pin is logic low, the
internal PLL is powered down and the external LO input is routed to the mixer LO inputs. The SPI can also be
used to switch modes.
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.
Mixer IF Outputs. These outputs should be pulled to VCC_MIX with RF chokes.
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.
