The EV8380 is an evaluation platform for the CMX838 Family Radio Processor. It speeds development time
by allowing CMX838 experiments to be performed without developing embedded host firmware.
The EV8380 includes a main PC board containing a CMX838 FRS/PMR446/GMRS Family Radio Processor,
a PCMCIA card and Windows^TM software. The main board includes interfaces to all CMX838 sections
including: RF (synthesizer RF input, charge pump output with loop filter, and synthesizer reference oscillator
input), audio (mic jack, mic bias source, and speaker amplifier, speaker output jack) and host (PC via
PCMCIA card and software).
Windows^TM software presents a ‘type and click’ interface to CMX838 registers for read and write operations.
It also executes tab-delimited text script files to automate command sequences.
The EV8380 supports all CMX838 baseband clock source modes including: connected baseband clock
crystal (included), derived from synthesizer reference oscillator and external baseband clock source.
The EV8380 main board can be used in a standalone manner or connected to external circuits for more
complete system testing. The main board is powered from an external 2.7-5.5VDC power supply.
The CMX838 data bulletin should be consulted during use of the EV8380.
