1.3
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
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
Regulatory
1.3.1
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
When calculating frequency deviation, bit rate, receiver
bandwidth, and PLL R, P and S values, use crystal
frequency f
1.3.3
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.
