RF block power supply
2
REXT
0.2
Connection for the external capacitor and resistor
used by the internal RF amplifier
3
RFIN
1
RF input
4
RFGND

Reception block power supply
7
CEXT
Connect a capacitor between the limiter reference
terminal for demodulated data waveshaping and
the GND terminal.
8
RXOUT
Demodulated data output
(CMOS output.)
9
LOCK DET
Outputs a high level when PN code
synchronization is established.
(This is a CMOS-level output.)
10
RXAOUT
