RFM210LW
5.6 Duty Cycle Receive Mode
In the duty-cycle mode, after the PUP the device will automatically repeat the sequence of SLEEP, XTAL, TUNE and RX until the
device is powered down. This allows the device to re-tune the synthesizer regularly to adept to the changeable environment and
therefore remain its highest performance. The device will continuously receive any incoming signals during the RX state and
send out the demodulated data on the DOUT pin. The PUP sequence consumes about 4 ms. See the figure below for the timing
and current consumption of the duty cycle receive mode
The advantages of the duty-cycle receive mode are listed below.
Maintaining the highest performance of the device by regular frequency re-tune.
Increasing the system stability by regular sleep (resetting most of the blocks).
If more current saving is required in the application, or other parameter need to be configured, the user can also use CMT2210A
or other NextGenRF^TM receivers with embedded EEPROM built-in and all product features configurable. For the more details,
please refer to the “AN108 CMT2210A Configuration Guideline”.
