Pin Description
ASK
CLK
FSK
Function
Clock output signal for the
microcontroller.
The clock output frequency is set by the
crystal to f
The CLK output stays Low in
power-down mode and after enabling of
the PLL.
The CLK output switches on if the
oscillation amplitude of the crystal has
reached a certain level.
Switches on the power amplifier for
ASK modulation and enables the PLL
and XTO if the ENABLE pin is open
Switches off the FSK switch (switch has
high Z if signal at pin FSK is High) and
enables the PLL and the XTO if the
ENABLE pin is open
