MOTOROLA ANALOG IC DEVICE DATA
Receive Audio Path
The Rx Audio signal path begins at “Rx Audio In” and goes
through the IC to “E Out”. The “Rx Audio In”, “Scr Out”, and
“E In” pins are all ac–coupled. This signal path consists of
filters; programmable Rx gain adjust, Rx mute, and volume
control, and finally the expander. The typical maximum
output voltage at “E Out” should be approximately 0 dBV @
THD = 5.0% .
Figures 71 to 73 represent the receive audio path filter
response. The filter response attenuation is very sharp above
3900 Hz, which is the cutoff frequency. Inband (audio),
out–of–band, and ripple characteristics are also shown in
these graphs.
The group delay (Figure 75) has a peak around 6.5 kHz.
This spike is formed by rapid change in the phase at the
frequency. In practice this does not cause a problem since
the signal is attenuated by at least 50 dB.
The output capability at “Scr Out” and “E Out” are shown in
Figures 76, 77, and 78. The results were obtained by
increasing the input level for 2.0% distortion at the outputs.
In Figure 70, noise data for the Rx audio path is shown.
At Scr Out, the noise level clearly rises when the scrambler is
enabled. However, assuming a nominal output level of –20
dBV (100 mVrms) at the 0 dB gain setting, the noise floor is
more than 56 dB below the audio signal. However, the noise
data at E Out and SA Out is much more improved.
Speaker Amp
The Speaker Amp is an inverting rail–to–rail operational
amplifier. The noninverting input is connected to the internal
VB reference. External resistors and capacitors are used to
set the gain and frequency response. The “SA In” input pin
must be ac–coupled. The typical output voltage at “SA Out” is
2.6 Vpp with a 130
load. The speaker amp response is
shown in Figures 79 and 80.
Data Amp Comparator
The data amp comparator is an inverting hysteresis
comparator. Its open collector output has an internal 100 k
pull–up resistor. A band pass filter is connected between the
“Det Out” pin and the “DA In” pin with component values as
shown in the Application Circuit schematic. The “DA In” input
signal needs to be ac–coupled, too.
