5.3 Operating Modes
The XE1202 has 4 main operating modes as set by the MODE[2:0] inputs and illustrated in table below. To switch
between modes, the new value of the inputs MODE[2:0] should be modified when the EN signal is low. The actual
change will be applied to the transceiver upon the rising edge of the EN signal.
Over the operating supply and temperature range, set-up and hold time for MODE[2:0] on the rising edge of EN are
200ns, while the negative pulse duration on EN is 2µs minimum.
5.3.1
3 additional operating modes are defined and should be used when the transceiver is switched from the standby
mode to the receiver or transmitter mode. These additional operating modes are illustrated in
