Operation
1.3.4
FREQUENCY SHIFT KEYING
The MRF89XAM8A module is based on the Microchip
Technology MRF89XA ultra-low power, integrated ISM
band sub-GHz transceiver IC. Serial communication
and module configuration are documented in the
“ MRF89XA Ultra-Low Power, Integrated ISM Band
MODULATION (FSK)
The following settings must be followed for FSK
modulation mode to conform to the European
standards summarized in Section 3.0, Regulatory
Approval .
Sub-GHz Transceiver Data Sheet ” (DS70622).
This section emphasizes operational settings that are
unique to the MRF89XAM8A module design that must
be followed in order for the module to conform to the
tested European standards summarized in Section 3.0,
Regulatory Approval .

Bit Rate Maximum Setting: 40 kbps
Frequency Deviation Maximum Setting: 40 kHz
Transmit Bandwidth Maximum Setting: 125 kHz
Lower Frequency Setting: 863.5 MHz
Upper Frequency Setting: 869.5 MHz
Note:
To maintain conformance to tested ETSI
standards, the module shall not be
1.3.5
ON-OFF KEYING MODULATION
(OOK)
modified and settings in Section 1.3,
Operation must be observed.
The following settings must be followed for OOK
modulation mode to conform to the European
1.3.1
RESET
standards summarized in Section 3.0, Regulatory
Approval .
Pin 2 of the module, RESET, enables an external reset
of the MRF89XA IC. RESET is connected to the TEST8
pin of the MRF89XA IC. During normal operations of
the MRF89XAM8A, the RESET pin should be held in a
high impedance state. For more information on
assertion of the RESET pin, refer to “ Section 3.1.2
Manual Reset ” of “ MRF89XA Data Sheet ” (DS70622).
1.3.2
CRYSTAL FREQUENCY
When calculating frequency deviation, bit rate, receiver
bandwidth, and PLL R, P and S values, use crystal
frequency f xtal = 12.8 MHz.
1.3.3
CLOCK OUTPUT (CLKOUT)
The CLKOUT pin 19 of the MRF89XA IC is not used on
the module. Ensure that the CLKOUT signal is disabled
to minimize current consumption.
