OMPAC
Analog-to-Digital converter; converts an instantaneous dc voltage level to a
corresponding digital value.
Custom integrated circuit providing a digital receiver IF backend.
Coder/Decoder IC for analog-to-digital and digital-to-analog conversion.
Customer Programming Software
Digital-to-Analog converter; converts a digital value to a corresponding dc
voltage value.
Digital Private-Line™
Digital Signal Processor; microcontroller specifically tailored for signal
processing computations. In this case refers specifically to Motorola
DSP56603.
Software or a software/hardware combination of computer programs and data,
with a fixed logic configuration stored in a read-only memory; information
can not be altered or reprogrammed.
Frequency Generation Unit
A Motorola term that describes the ability of a radio to change memory. Every
FLASHport radio contains a FLASHport EEPROM memory chip that can be
software written and rewritten to, again and again.
Motorola HC12A4 microcontrol unit U204 (see MCU).
Parallel memory mapped interface consisting of eight registers in the
DSP56603.
Integrated Circuit
Improved Multi-Band Excitation: a sub-band, voice encoding algorithm used
in ASTRO digital voice.
MicroControl Unit
Motorola Digital Communications
Master In Slave Out; used by the slave device to send data to the master device.
Master Out Slave In; used by the master device to send data to the slave device.
Over-Molded Pad-Array Carrier; a Motorola custom IC package, distinguished
by the presence of solder balls on the bottom pads.
