MOTOROLA RF/IF DEVICE DATA
strongly recommended to minimize coupling of any digital
noise into the analog section. Use of wire wrapped boards
should definitely be avoided.
Since many applications of the MC33110 compander
involve voice transmission over RF links, care must be taken
in the design of the product to keep RF signals out of the
MC33110 and associated circuitry. This involves proper
layout of the PC boards, the physical arrangement of the
boards, shielding, proper RF ground, etc.
GLOSSARY
Attack Time —
The settling time for a circuit after its input
signal has been increased.
Attenuation —
A decrease in magnitude of a
communication signal, usually expressed in dB.
Bandwidth —
The range of information carrying frequencies
of a communication system.
Channel Separation —
The ability of one circuit to reject
outputting signals which are being processed by another
circuit. Also referred to as crosstalk, it is usually expressed in
dB.
Compander —
A contraction of the words compressor and
expander. A compander is composed of two circuits, one of
each kind.
Compressor —
A circuit which compresses or reduces the
dynamic range of a signal by attenuating strong signals and
amplifying low level signals.
dB —
A power or voltage measurement unit, referred to
another power or voltage. It is generally computed as:
10 x log (P1/P2) for power measurements, and
20 x log (V1/V2) for voltage measurements.
dBm —
An indication of signal power. 1.0 mW across 600
or 0.775 V rms, is typically defined as 0 dBm for telecom
applications. Any voltage level is converted to dBm by:
dBm = 20 x log (Vrms/0.775), or
dBm = [20 x log (Vrms)] + 2.22.
dBrn —
Indicates a dBm measurement relative to 1.0 pW
power level into 600
. Generally used for noise
measurements, 0 dBrn = – 90 dBm.
dBrnC —
Indicates a dBrn measurement using a
C–message weighting filter.
Decay Time —
The settling time for a circuit after its input
signal has been decreased.
Expander —
A circuit which expands or increases the
dynamic range of a signal by amplifying strong signals and
attenuating low level signals.
Gain —
The change in signal amplitude (increase or
decrease) after passing through an amplifier, or other circuit
stage. Usually expressed in dB, an increase is a positive
number and a decrease is a negative number.
Power Supply Rejection Ratio —
The ability of a circuit to
reject outputting noise, or ripple, which is present on the
power supply lines. PSRR is usually expressed in dB.
Signal–to–Noise Ratio —
The ratio of the desired signal to
unwanted signals (noise) within a defined frequency range.
The larger the number, the better.
Voiceband —
That portion of the audio frequency range
used for transmission across the telephone system.
Typically, it is 300 to 3400 Hz.
