For best results, these pins should be connected to the ground plane
against which the antenna radiates
Nominal 50 ohm input/output impedance capacitively isolated from
internal circuit. See application notes for antenna examples
Supply ground points
Not connected internally
RF gnd only on X2011
Receiver signal strength indicator
DC voltage proportional to RF signal strength being received
Digital Carrier Detect Output – Active Low
Receiver digital data output (CMOS logic out) representing true data as
supplied to the transmitter
Audio Frequency Output
Data input to the transmitter can be directly interfaced to CMOS logic
drive operating on the same supply voltage as the transceiver
Active Low
Applying Vcc disables the transmitter
Active Low
Applying Vcc places the receiver in sleep mode
Supply voltage range from 4.5 to 5.5volts. Note that module is not
reverse polarity protected
