NAME

FUNCTION

DC Power Supply for Synthesizer Circuits. Connect to a +3.3V low-noise supply. Bypass to GND with

13

VCC_SYN a 1nF capacitor connected as close as possible to the pin. Do not share capacitor ground vias with

other ground connections.

14

XTAL

Crystal-Oscillator Interface. Use with an external parallel-resonance-mode crystal by a series 1nF

capacitor. See the Typical Operating Circuit.

15

REFOUT

Crystal-Oscillator Buffer Output. A DC-blocking capacitor must be used when driving external

circuitry.

DC Power Supply for Digital Logic Circuits. Connect to a +3.3V low-noise supply. Bypass to GND

16

VCC_DIG with a 1nF capacitor connected as close to the pin as possible. Do not share capacitor ground vias

with other ground connections.

17

QOUT+

Quadrature Baseband Differential Output. AC-couple with a 47nF capacitor to the demodulator input.

21

IDC+

I-Channel Baseband DC Offset Correction. Connect a 47nF ceramic chip capacitor from IDC- to

22

IDC-

IDC+.

23

QDC+ Q-Channel Baseband DC Offset Correction. Connect a 47nF ceramic chip capacitor from QDC- to

24

QDC- QDC+.

DC Power Supply for Baseband Circuits. Connect to a +3.3V low-noise supply. Bypass to GND with a

25

VCC_BB 1nF capacitor connected as close as possible to the pin. Do not share capacitor ground vias with

other ground connections.

26

SDA

2-Wire Serial-Data Interface. Requires a ≥ 1kΩ pullup resistor to VCC.

27

SCL

2-Wire Serial-Clock Interface. Requires a ≥ 1kΩ pullup resistor to VCC.

28

ADDR Address. Must be connected to either ground (logic 0) or supply (logic 1).
