A special type of PROM that can be erased by exposing it to an
electrical charge. An EEPROM retains its contents even when the
power is turned off.
Federal Communications Commission.
Code executed by an embedded processor such as the Host or DSP in
a subscriber radio. This type of code is typically resident in non-volatile
memory and as such is more difficult to change than code executed
from RAM.
See frequency generation unit.
A non-volatile memory device similar to an EEPROM. Flash memory
can be erased and reprogrammed in blocks instead of one byte at a
time.
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.
See Field Manual Revision..
A publication that provides supplemental information for its parent
publication before it is revised and reissued.
Field Programmable Gate Array.
Number of times a complete electromagnetic-wave cycle occurs in a
fixed unit of time (usually one second).
This unit generates ultra-stable, low phase noise master clock and other
derived synchronization clocks that are distributed throughout the
communication network.
See integrated circuit.
Intermediate Frequency.
An assembly of interconnected components on a small semiconductor
chip, usually made of silicon. One chip can contain millions of
microscopic components and perform many functions.
See kilohertz.
One thousand cycles per second. Used especially as a radio-frequency
unit.
See liquid-crystal display.
See light emitting diode.
An electronic device that lights up when electricity is passed through it.
