Description
+1.8 to +3.6 V supply voltage input to all analog +1.7 V regulators. The recommended V DD supply voltage
is +3.3 V.
No Connect.
RV input pin to LNA. See application schematic.
No Connect. Not connected internally to any circuitry.
No Connect
General Purpose Digital I/O that may be configured through the registers to perform various functions
including: Microcontroller Clock Output, FIFO status, POR, Wake-Up timer, Low Battery Detect, etc. See
the SPI GPIO Configuration Registers, Address 0Bh, 0Ch, and 0Dh for more information.
Regulated Output Voltage of the Digital 1.7 V Regulator. A 1 μF decoupling capacitor is required.
Internally this pin is tied to the paddle of the package. This pin should be left unconnected or connected to
GND only.

+1.8 to +3.6 V supply voltage input to the Digital +1.7 V Regulator. The recommended V DD supply voltage
is +3.3 V.
0–V DD V digital output that provides a serial readback function of the internal control registers.
Serial Data input. 0–V DD V digital input. This pin provides the serial data stream for the 4-line serial data
bus.
Serial Clock input. 0–V DD V digital input. This pin provides the serial data clock function for the 4-line
serial data bus. Data is clocked into the Si4313 on positive edge transitions.
Serial Interface Select input. 0– V DD V digital input. This pin provides the Select/Enable function for the 4-
line serial data bus. The signal is also used to signify burst read/write mode.
General Microcontroller Interrupt Status output. When the Si4313 exhibits anyone of the Interrupt Events
the nIRQ pin will be set low=0. Please see the Control Logic registers section for more information on the
Interrupt Events. The Microcontroller can then determine the state of the interrupt by reading a corre-
sponding SPI Interrupt Status Registers, Address 03h and 04h. No external resistor pull-up is required,
but it may be desirable if multiple interrupt lines are connected.

Crystal Oscillator Input. Connect to an external 30 MHz crystal or leave floating if driving XOUT with
external signal source or TCXO.

Shutdown input pin. 0–V DD V digital input. SDN should be = 0 in all modes except Shutdown mode. When
SDN =1 the chip will be completely shutdown and the contents of the registers will be lost.
The exposed metal paddle on the bottom of the Si4313 supplies the RF and circuit ground(s) for the entire
chip. It is very important that a good solder connection is made between this exposed metal paddle and
the ground plane of the PCB underlying the Si4313.
