Description
1
XIN
I
Crystal connection or external frequency input. This pin has dual functions.
It can be connected to either an external crystal or an external reference
clock.
2
XOUT
O
Connection for an external crystal. If using an external reference, this pin
must be left unconnected.
3
GND
P
Ground to entire chip.
4
SS%
I
Spread range select. Digital logic input used to select frequency deviation
(Refer Spread Deviation Selection Table). This pin has an internal pull-up
resistor.
5
ModOUT
O
Spread spectrum low EMI output.
6
VDD
P
Power supply for the entire chip (3.3V).
7
FS0
I
Frequency range select. Digital logic input used to select frequency range
(Refer Input Frequency and Modulation Rate Table). This pin has an internal
pull-up resistor.
8
FS1
I
Frequency range select. Digital logic input used to select frequency range
(Refer Input Frequency and Modulation Rate Table). This pin has an internal
pull-up resistor.
