Description
Serial Clock Input.
12
SCLK
I
0–VDD V digital input. This pin provides the serial data clock function for the
4-line serial data bus. Data is clocked into the Si4463/61 on positive edge tran-
sitions.
13
SDO
O
0–VDD V Digital Output.
Provides a serial readback function of the internal control registers.
Serial Data Input.
14
SDI
I
0–VDD V digital input. This pin provides the serial data stream for the 4-line
serial data bus.
Serial Interface Select Input.
15
nSEL
I
0–VDD V digital input. This pin provides the Select/Enable function for the
4-line serial data bus.
Crystal Oscillator Output.

cuit ground(s) for the entire chip. It is very important that a good solder connec-
tion is made between this exposed metal paddle and the ground plane of the
PCB underlying the Si446x.
