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

Notes
1. Sleep mode, that is with tx and rx not enabled
2. 1 Hz = 2 bps
3. The data slicer is optimised for a 50:50 duty cycle hence for reliable communications data
should be encoded using a suitable scheme such as Manchester Encoding, although pulse
width modulation up to 70:30/30:70 can also be used.
