Notes
1.
Xtal/clock operation
Operation of any MX-COM IC without a Xtal or
clock input may cause device damage. To minimize
damage in the event of a Xtal/drive failure, you
should install a current limiting device (resistor or
fast-reaction fuse) on the power input (V
DD
).

SAT Output
It is possible, due to the impedance of this output,
that an external buffer amplifier will be required
when interfacing or mixing with other cellular system
sections.
