FM Narrow Band Transceiver Modules X2010 / X2011
Features
• Operation on 434.075, 868.40 and 914.5 MHz
• X2011 version includes integrated pcb loop
antenna (434 & 868 MHz versions)
• Double RF filtering = High Reliability RF Link
• Data rates to 20 kbps (Wide-band 64 kbps
version available to order)
• -112 dBm receiver sensitivity (434 version)
• CD and RSSI outputs
• Crystal stabilised accurate RF, hence
narrower BW filter utilised
• Results in over 300m range
• EN 300 220-1, 300 683 & FCC compliant
• Immune to Tetra and High power Radio
Amateur Repeater Stations
Applications
• EPOS Terminals
• Wireless Networking
• Domestic And Commercial Wireless Security
Systems
• Panic Attack Facility
• Remote Control For Cranes Etc
General Description
The X2010 radio transceiver module was
designed to provide reliable wireless operation at
moderate data rates for use throughout the world.
Its unique features of narrower RF channel
bandwidths and hence high interference rejection
capability at SAW module prices make the X2010
the ideal choice for next generation applications.
Available at several frequency options, these
modules have been designed to provide a reliable
wire free link within the presence of other
interference at the same frequency, accounting for
the increased traffic from other legal users of the
radio spectrum
The transmitter section uses a PLL design that
utilises a highly stable and accurate reference
crystal oscillator. This results in a RF transmission
tightly controlled in its frequency spread and over
its operating temperature range. This is exploited
in the receiver design.
The receiver section uses a single conversion
super-het design, again using PLL technology.
Hence narrower bandwidth RF filters are utilised
which result in superior rejection of interference as
well as providing good receiver sensitivity and
hence range

Details
Ideally connected to antenna ground plane.
Nominal 50 ohm input/output impedance capacitively isolated from
internal circuit.
Not connected internally on X2010 module.
X2010 : This is unconnected
X2011 : RF Ground.
Receiver signal strength indicator. DC voltage proportional to the RF
signal strength being received.
Supply ground points.
Carrier detect output, active low.
Receiver data output ( CMOS logic out )
Audio frequency output.
Transmitter data input.
Active low, applying Vcc disables the transmitter.
Active low, applying Vcc places the receiver in sleep mode.

Mode
Power down mode. Supply current <1uA
Receiver only enabled. Data, AF, CD and RSSI outputs valid.
Transmitter only enabled. Tx data input valid.
Tx and Rx enabled. This mode is to be avoided as damage to the
module will eventually occur.
RSSI Output
The RSSI output provides a dc voltage that is proportional to the RF signal strength picked up on the
antenna (pin 2) port of the module.
The table below gives typical values of RSSI for varying degrees of RF signal strength applied
