DESCRIPTION
Supply Voltage for Digital Circuitry. Bypass with a capacitor as close to the pin as possible. Do not
share the bypass capacitor ground vias with other branches.
No Connection. Not internally connected.
Reference Oscillator Positive Input. Analog high-impedance differential input. DC-coupled. Requires
external AC-coupling. Connect an external reference oscillator to this analog input.
Reference Oscillator Negative Input. Analog high-impedance differential input. DC-coupled. Requires
external AC-coupling. Bypass this analog input to ground with a capacitor for single-ended operation.
3-Wire Serial-Interface Data Input. Digital high-impedance input. Connect directly to baseband IC
serial-interface CMOS output (SPI ? /QSPI ? /MICROWIRE ? compatible).
3-Wire Serial-Interface Clock Input. Digital high-impedance input. Connect this digital input directly to
baseband IC serial-interface CMOS output (SPI/QSPI/MICROWIRE compatible).
3-Wire Serial-Interface Enable Input. Digital high-impedance input. Connect directly to baseband IC
serial-interface CMOS output (SPI/QSPI/MICROWIRE compatible).
Supply Voltage for PLL Charge Pump. Bypass with a capacitor as close to the pin as possible. Do not
share the bypass capacitor ground vias with other branches.
PLL Charge-Pump Output. Analog high-impedance output. Current source. Connect directly to the
PLL loop filter input.
PLL Charge-Pump Ground. Connect to PC board ground plane.
VCO Ground. Connect to PC board ground plane.
VCO Frequency Tuning Input. Analog high-impedance voltage input. Connect directly to the PLL loop
filter output.
VCO Bias Bypass. Bypass with a 2000pF capacitor to ground.
Supply Voltage for VCO. Bypass with a capacitor as close to the pin as possible. Do not share the
bypass capacitor ground vias with other branches. Important note: Operate from separate regulated
supply voltage.
Supply Voltage for VCO, LO Buffers, and LO Quadrature Circuitry. Bypass with a capacitor as close
to the pin as possible. Do not share the bypass capacitor ground vias with other branches.
Supply Voltage for Receiver Baseband Filter. Bypass with a capacitor as close to the pin as possible.
Do not share the bypass capacitor ground vias with other branches.
Active-Low Shutdown Input. Digital high-impedance CMOS input. Connect directly to baseband IC
mode control CMOS output. Logic low to disable all device functions. Logic high to enable normal
chip operation.
Serial-Interface Data Output . Digital CMOS output. Optional connection.
Receiver 1kHz Highpass Bandwidth Control. Digital CMOS input. Connect directly to baseband IC
CMOS output. Controls receiver baseband highpass -3dB corner frequency; logic low for 10kHz,
logic high for 1kHz. See the Applications Information section for proper use of this function.
